Add a new `base58` crate to the workspace and move the `bitcoin::base58`
module to it.
Done as part of crate smashing, specifically so that we can make `bip32`
into a separate crate.
We attempted to release with the current 0.1.0 version forgetting that
we had previously released an empty crate with that version to reserve
the name on crates.io.
Bump the version to 0.1.1 and release the actual code.
At times we would like to provide types that do not implement
`PartialOrd` and `Ord` because it does not make sense. I.e., we do not
want users writing `a < b`. This could range from kind-of-iffy to
down-right-buggy (like comparing absolute locktimes).
However this decision effects downstream users who may not care about
what the ordering means they just need to use it for some other reason
e.g., to use as part of a key for a `BTreeMap` (as we do in `miniscript`
requiring the `AbsLockTime` type).
A solution to this problem is to provide a wrapper data type that adds
`PartialOrd` and `Ord` implementations. I wrote the `ordered` crate is
for this very purpose.
Feature gate a new dependency on `ordered` and implement `ArbitraryOrd`
for `absolute::LockTime`.
Currently `bitcoin` cannot be built with no features enabled, it must
have either "no-std" or "std" enabled. This is an artifact from when
we depended on `core2` for "no-std", now that we have our own `io` crate
and we unconditionally depend on it we can remove the "no-std" feature.
Currently the feature enabling is different for "std" and "no-std",
which is again different to the order in the dependencies section. These
two things make reading the manifest harder than it needs to be.
Put the dependencies in alphabetic order in the dependencies section as
well as when enabling them.
Refactor only, no logic changes.
Its not immediately obvious why we nest the whole `io` code in an `io`
submodule within `lib.rs`. As far as I can tell we can inline it and
re-export from `rust-bitcoin` same as we do for our other dependencies.
This change would effect other users of the crate but since the `io`
crate is unreleased this effects no-one except us.

d9cc724187 Bump MSRV to Rust version 1.56.1 (Tobin C. Harding)
Pull request description:
Rust version 1.56.0 introduced edition 2021. Shortly afterwards, on October 21 2021 Rust version 1.56.1 was released.
Debian stable is currently shipping `rustc 1.63.0`. Our stated MSRV policy is: In Debian stable and at least 2 years old. Therefore our MSRV policy is met by Rust version 1.56.1 and we can strat to bump our MSRV org wide. Start by bumping the `rust-bitcoin` and `hashes` MSRV to Rust 1.56.1
Start by bumping the `rust-bitcoin` and `hashes` MSRV to Rust 1.56.1, includes:
- Update docs.
- Update CI and remove pinning.
- Update the build files and remove now stale cfg attributes rust_v_1_x for values less than the new MSRV.
- Use new `IntoIterator` for arrays so we no longer need to allocate a vector to iterate.

fa104aefa5 bitcoin: Add signing examples (Tobin C. Harding)
Pull request description:
Add two signing examples to showcase signing a simple one input two output transaction using both segwit v0 outputs and taproot outputs.
This patch is the result of the recent rust-bitcoin TABConf workshop, with bug fix by Sanket, updated to use APIs from tip of master branch.
This code, depending on v0.30.0 is what was added to the cookbook.

We do not need this dependency because we can get the serde derives
directly from `serde`.

In order to support standard (de)serialization of structs, the
`rust-bitcoin` ecosystem uses the standard `std::io::{Read,Write}`
traits. This works great for environments with `std`, however sadly
the `std::io` module has not yet been added to the `core` crate.
Thus, in `no-std`, the `rust-bitcoin` ecosystem has historically
used the `core2` crate to provide copies of the `std::io` module
without any major dependencies. Sadly, its one dependency,
`memchr`, recently broke our MSRV.
Worse, because we didn't want to take on any excess dependencies
for `std` builds, `rust-bitcoin` has had to have
mutually-exclusive `std` and `no-std` builds. This breaks general
assumptions about how features work in Rust, causing substantial
pain for applications far downstream of `rust-bitcoin` crates.
Here, we add a new `bitcoin_io` crate, making it an unconditional
dependency and using its `io` module in the in-repository crates
in place of `std::io` and `core2::io`. As it is not substantial
additional code, the `hashes` io implementations are no longer
feature-gated.
This doesn't actually accomplish anything on its own, only adding
the new crate which still depends on `core2`.
Add two signing examples to showcase signing a simple one input two
output transaction using both segwit v0 outputs and taproot outputs.
This patch is the result of the recent rust-bitcoin TABConf workshop,
wit bug fix by Sanket, updated to use APIs from tip of master branch.
This code, depending on v0.30.0 is what is being introduced to the
cookbook at the moment.
Upgrade the `secp256k1` dependency to the newly released `v0.28.0`.
FTR this includes two simple changes:
- Use `Message::from_digest_slice` instead of `Message::from_slice`.
- Use `secp256k1::Keypair` instead of `secp256k1::KeyPair`.
Update the `bech32` dependency to use the newly release beta version.
The main fix here is silent, a bug fix in `bech32` that was being hit by
our fuzzing suite.

We have just released the `hex-conservative` crate, we can now use it.
Do the following:
- Depend on `hex-conservative` in `bitcoin` and `hashes`
- Re-export `hex-conservative` as `hex` from both crate roots.
- Remove all the old hex code from `hashes`
- Fix all the import statements (makes up the bulk of the lines changed

We use two different methods for specifying local dependencies, `patch`
and also `path`. There does not seem to be a reason why we use both,
lets be uniform. Elect to use `patch` for all local crates.
In preparation for release bump the version and add a changelog entry.
Includes updating the dependency in `bitcoin` and `hashes` as well as
the minimal/recent lock files.
This implements basic facilities to conditionally carry string inputs in
parse errors. This includes:
* `InputString` type that may carry the input and format it
* `parse_error_type!` macro creating a special type for parse errors
* `impl_parse` implementing parsing for various types as well as its
`serde`-supporting alternative
We can use `package` to rename `bitcoin_hashes` to `hashes` and
`bitcoin_internals` to `internals`. This makes imports more terse with
no loss of meaning.
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.
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.
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.
In `bitcoin` when we use the `core2` dependency we always need the
"alloc" feature. Enabling "alloc" when enabling "core2" in the "no-std"
feature is confusing because it makes it seem that we don't always need
it.
Set usage of the "alloc" feature of `core2` in the `features` list.
`core2` is for Read/Write, nothing to do with allocation and we do not
use the "alloc" feature of `core2` in `hashes`.
Fix core2 dependency/features by doing:
- Explicitly enable "bitcoin_hashes/core2" in `bitcoin`.
- Do not enable "core2/alloc" in `hashes`
Improve all manifest package sections by doing:
- Order the list of options uniformly
- Remove unnecessary homepage option (currently same as repo)
- Add categories section
