This adds a conversion function to U256 to get an f64. We use the method shown in the following blog post. https://blog.m-ou.se/floats/
Target::MAX was converted to a f64 and set as a const that is verified in a unit test.
bfd401c96e bitcoin_hashes: add CHANgELOG (Andrew Poelstra)
d1b7b54e3a bump bitcoin-hashes version to 0.12 (Andrew Poelstra)
Pull request description:
It was a little tricky to bump the version number because of https://github.com/rust-bitcoin/rust-bitcoin/issues/1553. There are a couple other things I considered trying, which maybe we'll do for future releases, but I believe this works for now.
Maybe should wait for #1111.

3eb648df01 Add constants to `InputWeightPrediction` (Martin Habovstiak)
Pull request description:
There are several common spends in Bitcoin that have known input weight predictions. It can be useful to have these as constants, so this change adds them. However, this only adds native segwit ones as the others are slowly fading away and might clutter the API.
If anyone wants other constants, please write them for me, their value is not that great to me so I'm not motivated to figure out the correct numbers. :)
This would be nice to add to 0.30 since it's small and easy but not critical.

Enable formatting in CI by doing:
- Add a section to the `test.sh` scripts to run the formatter (guarded by
the env variable `DO_FMT`) for all crates (bitcoin, hashes, internals).
- Add `DO_FMT` to the nightly `Tests` CI job.
Various formatting issues have crept into the codebase because we do not
run the formatter in CI.
In preparation for enabling formatting checks in CI run `cargo +nightly
fmt` to fix current formatting issues. No changes other than those
create by the formatter.
Because we have rust-secp in the loop, we need to update rust-secp, push
a new tag, and use that here, to ensure that the direct dependency on
bitcoin_hashes, and the rust-secp version, are compatible.

38ed9bdf49 MOVE ONLY: Move TapTree to taproot module (sanket1729)
Pull request description:
This PR changes/removes the serde implementation for the following types
- TaprootSpendInfo: Removed. This data structure contains derived information for taproot spending that cannot be validated easily. To elaborate, `TaprootSpendInfo` is constructed from a tree, but loses information about the tree structure and maintains handy information like `script_control_block_map`, cached tweaked key, Merkle root etc.
- TaprootBuillder: Removed. Hard to implement and not very useful.
- TapTree: Modified to check invariants.
- NodeInfo: Now implements serde with support for Hidden nodes
- ScriptLeaf: Removed serde. Users should not directly construct this. This is just an output iterator item of `TapTree::script_leaves()`
Data structure changes:
- Introduced `LeafNode`: Supports Hidden leaves. Has serde implemented
- Cleanly separate `TapTree` and `NodeInfo`: `TapTree` is a full BIP370 compatible tree with no hidden nodes. `NodeInfo` is a tree that can potentially contain hidden leaves.
- Added `NodeInfo::leaf_nodes`: Iterator that iterates over known and hidden leaves of `NodeInfo`.
- Updated `TapTree::script_leaves`: Iterator that is guaranteed to output known leaves.

73e876ffd4 Include address in Error::NetworkValidation (Subhradeep Chakraborty)
Pull request description:
Fixes: #1677
## Change
In `bitcoin/src/address.rs`, a new field `address` is added to the enum variant `Error::NetworkValidation`. Also, the implementation of `Display` trait for `Error` is updated to print the `address` field.
However, to print the `address` through `Display`, either the reference is needed or `Address` and `Payload` both need to derive the `Copy` trait. Since I am little new to both the rust-bitcoin codebase and rust itself, I am confused about choosing between the two and have moved with the first one. Would appreciate any feedback on this.

Implementing this for spendinfo is really complicated because it
contains some cached data without retaining the components that are used
to compute them.
Users should serde the 1) NodeInfo and 2) internal key and reconstruct
TaprootSpendInfo from it.
This was incorrect and not needed. Users should not be able to create
only tree leaves directly without going through the tree construction in
rust-bitcoin

161273b209 Re-name hash inner/byte methods (Tobin C. Harding)
324b6f264b Use `into` for hash argument (Tobin C. Harding)
Pull request description:
Currently we have an associated type on hash types `Inner` with accompanying methods `into_inner`, `from_inner`, `as_inner`. Also, we provide a way to create new wrapped hash types. The use of 'inner' becomes ambiguous with the addition of wrapped types because the inner could be the inner hash type or the `Inner` byte array of the inner wrapped hash type.
In an effort to make the API more clear and uniform do the following:
- Rename `Inner` -> `Bytes`
- Rename `*_inner` -> `*_byte_array`
- Rename the inner hash to/from methods to `*_raw_hash`
Correct method prefix `into_` -> `to_` because theses methods convert owned `Copy` types.
Add the trait Bound `Copy` to the `Bytes` type because we rely on this trait bound for the conversion methods to be correctly named according to convention.
Because of the dependency hole created by `secp256k1` this patch changes the secp dependency to a git tag dependency that includes changes to the hashes calls required so that we can get green lights on CI in this repo.

"schnorr" is a dirty word; the current `schnorr` module defines a
`Signature` that includes a sighash type, this sighash type is a bitcoin
specific construct related to taproot. Therefore the `Signature` is
better named `taproot::Signature`. Note also that the usage of `schnorr`
in `secp256k1` is probably justified because the
`secp256::schnorr::Signature` is just doing the crypto.
While we are at it, update docs and error messages to use "taproot"
instead of "schnorr". Also change function names and identifiers that
use "schnorr".
Currently we have `TapSighash` that is used for taproot sighashes but
for non-taproot sighashes we use `hash_types::Sighash`. We can improve
the API by creating a `LegacySighash`, and `SegwitV0Sighash`.
Copy the original `Sighash` macro calls to create the two new types in
the `sighash` module.
While we are at it, put the `TapSighash` and `TapSighashTag` into the
`sighash` module also.
There is never any use for the `sighash` module unless one is signing,
which requires the `crypto` module. The `sighash` module should
therefore live in the `crypto` module. This is not an API breaking
change because we reexport it at the crate root.
`Signature` only supported serialization into `Vec` which required a
heap allocation as well as prevented statically proving maximum length.
Adding a specialized type that holds a byte array and size solves this.
The solution is very similar to `secp256k1::ecdsa::SerializedSignature`.
The difference is that serialized signature in this crate contains
sighash bytes flag while in `secp256k1` it doesn't.
Script parsing is composed of several functions which implicitly rely on
various properties. Adding a type that restricts the valid values makes
local review easier.
So far we deserialized hex into `Vec<u8>` at run time. This was mainly
in tests where it had negligible performance cost. However moving the
computation to compile time has a few benefits: it allows proving the
length of the decoded bytes and identifies potential typos before the
code goes through LLVM and other compilation machinery which makes
feedback faster.
This change uses the `hex_lit` crate to move computation to compile
time. It is implemented as `const` declarative macro which doesn't blow
up compilation time.
a121e19e94 hashes: Implement AsRef for fixed size arrays (Tobin C. Harding)
Pull request description:
Implement `AsRef<[u8; X]>` for hash types including wrapped hash types. Doing so means at times the compiler can no longer infer the type because we have `AsRef<[u8]` implemented also but we can use `into_inner` and `as_inner` to get the inner array if needed.
Fix: #1462
## Note
This touches code that will likely be changed by #1577 and when we do #1491 but I believe its a step forward.

When we added `Target` and `Work` types we implemented multiplication and division by anything `Into<u64>`, this is not typically done in the Rust stdlib and also is semantically incorrect for the types.
Remove `Mul` and `Div` impls from `Target` and `Work`. Also remove `Mul<T>` for `T: Into<u64>` from the private `U256` type.

272cdbcf7c Flatten the types directory (Tobin C. Harding)
Pull request description:
We recently created a `types` subdirectory under `script` to keep all the `Script` and `ScriptBuf` impls together. Turns out this additional level of subdirectory is a bit annoying and we can achieve the same grouping by just using `script/mod.rs`.
Move code from `types/mod.rs` to `script/mod.rs`, move the two submodules up a level, remove the `types` directory.

ae2aaaa436 Add `script_pubkey_lens` method (Martin Habovstiak)
cf068d16b0 Implement transaction weight prediction (Martin Habovstiak)
Pull request description:
When creating a transaction one must know the the fee beforehand to set
appropriate amounts for outputs and to know the fee, weight is required.
So far we only had a method on an already-constructed transaction. This
method clearly wasn't helpful when constructing the transaction except
for hacks like temporarily adding an all-zeroes signature.
This change adds a function that can compute the transaction weight
without knowing individual bytes of the scripts, witnesses and other
elements. It only needs to know their sizes.
To make the API less error-prone a special, trivial, type is also added
for computing the lengths of witnesses.
Based on #1627

6be89bf94f Add `minimal_non_dust` to `TxOut` (Martin Habovstiak)
Pull request description:
In some scenarios it's useful to create outputs with minimal relayable value. E.g. outputs designated for fee bumping using CPFP. A method for this is useful.
This implements a constructor of `TxOut` that computes the minimal non-dust value from the passed script.
Closes#1459
This one is quite easy, so if we could get it in 0.30, that'd be great.

Move code from `types/mod.rs` to `script/mod.rs`, move the two

In some cases people construct the transaction with a dummy fee output
value before calculating the weight. A method to create the iterator
over `script_pubkey` lengths is useful in such cases.

Pull request description:
When we introduced the SPDX license blurb in [0] we incorrectly gave attribution to Andrew when the original file author had the attribution as "the rust-bitcoin developers". The original author [1] was Tamas Blummer and he copied this code from code he wrote and explicitly re-licenses it. In order to make the re-licensing comment a little clearer and fix the mis-attribution use Tamas' name in the attribution.

Currently the docs build commands in `hashes` and `bitcoin` differ, they should be the same.
Add a command `cargo doc` to improve coverage e.g., recently we botched the feature guarding but since CI only runs `cargo rustdoc` with custom compiler conditional set we didn't catch it.
Done after seeing: https://github.com/rust-bitcoin/rust-bitcoin/pull/1504 and CI should fail on this PR until 1504 is in.

Pull request description:
Patch one does the deprecation, the rest of the PR is made up of tiny improvements to the code around reading/writing 'scriptint's (conceptually `CScriptNum`s). I did all this while trying to decipher the discussion on #1547.
### Note Please
There are many more changes in the pipeline for all this read/write "script int" stuff. This PR was done ages ago and I believe it stall adds value.
I re-did the whole PR manually because of the recent `script` module changes. I hope no one else has to do that - if you do please feel free to holla and I'll "rebase" your PR for you.

Lock times are `u32` and can require encoding using 5 bytes.
Add methods `push_lock_time` and `push_sequence` for pushing absolute lock times and sequence numbers. We do not push relative locktimes because they are only 16 bits from the original sequence number.

Do a complete overhaul of the manifest of the top level crates (i.e., not `embedded`, `fuzzing` ect.).
Many of the problems being fixed here were introduced over the last year by my poor understanding of exactly what was going on with _every_ line of code in the manifests, after this PR I hope that is no longer a problem.
I'm closing #1571 because it is now done more fully at the end of this PR.
During review please be liberal with any questions so we can ensure everything is spot on now - as we add more crates there are going to be a proliferation of manifest files, best get it right now.

Pull request description:
PR 2 in the `merkle_tree::block` series, used to be on top of the now merged #1374.
Do a bunch of refactorings in preparation for more invasive changes. This is a separate PR because, other than the first patch which moves hex strings to `tests/data/` the other patches are refactoring only patches, no logic changes. However the last patch is big and will be annoying to review - sorry about that. If you really oppose this basically stylistic patch putting important things first, the opposite of C code, please say and I'll try to stop doing it.

Currently we implement string parsing for height/time from the
`absolute` module but not the `relative` module.
Improve the macros used to implement string parsing and use the new
versions to implement string parsing for the height and time types in
`relative`.
Lock times are u32 and can necessitate encoding using 5 bytes. As such
they are "special".
Add methods `push_lock_time` and `push_sequence` for pushing absolute
lock times and sequence numbers. We do not push relative locktimes
because they are only 16 bits from the original sequence number.
Our `script::read_scriptint` function is based on the constructor
code (incl. call to `set_vch`) code from Bitcoin Core. Add rustdoc
comment saying so, emit a link because there are already multiple links
to `script.h` in this file (one just right below the added comment).
We only support reads of upto 4 bytes where as Bitcoin Core allows
reading a `CScriptNum` with more bytes than that. Add a rustdoc
comment (incl. link to Bitcoin Core) mentioning that.
Our `Builder::push_int` method is the same as Bitcoin Core `CScript`
`push_int64` method. We currently use `OP_FALSE` (equivalent to `OP_0`)
but recently we added `OP_0`, lets use it to make our code better mimic
Core (also saves devs checking that `OP_FALSE` is the same as `OP_0`).
