I hope putting it on the most notorious type where people actually notice it is enough. I couldn't find a good way to put it on all other `sha256d` automatically, and copy pasting it seems not worth it.

Add non_exhaustive compiler directive to AddressType
Currently adding variants to enums is a breaking change. In an effort to
reduce the upgrade burden on users we can use the `non_exhaustive`
compiler directive so that adding a new variant does not cause
downstream code to break.
Add `non_exhaustive` to the `AddressType` since it may be extended in
the future.

Adding an error variant to a public enum is an API breaking change, this
means making what could be small refactorings or improvements harder. If
we use `non_exhaustive` for error types then we mitigate this cost.
There is a tradeoff however, downstream users who explicitly match on
our public error types must include a wildcard pattern.
As things are right now, memory exhaustion protection in `Decodable`
is based on checking input-decoded lengths against arbitrary limits,
and ad-hoc wrapping collection deserialization in `Take`.
The problem with that are two-fold:
* Potential consensus bugs due to incorrect limits.
* Performance degradation when decoding nested structured,
due to recursive `Take<Take<..>>` readers.
This change introduces a systematic approach to the problem.
A concept of a "size-limited-reader" is introduced to rely on
the input data to finish at enforced limit and fail deserialization.
Memory exhaustion protection is now achived by capping allocations
to reasonable values, yet allowing the underlying collections
to grow to accomodate rare yet legitmately oversized data (with tiny
performance cost), and reliance on input data size limit.
A set of simple rules allow avoiding recursive `Take` wrappers.
Fix#997
A better way to write a byte string is to use write all so that
`ErrorKind::Interupted` is not returned.
Use `write_all` to write the non-sense (error indication) string to the
writer when we hit the SIGHASH_SINGLE bug.
Rust convention is to use `to_` for conversion methods that convert from
an owned type to an owned `Copy` type. `as_` is for borrowed to borrowed
types.
Re-name and deprecate conversion methods that use `as_` for owned to
owned `Copy` types to use `to_`.
Rust convention is to use `to_` for conversion methods that convert from
an owned type to an owned `Copy` type. `into_` is for owned to owned
non-`Copy` types.
Re-name and deprecate conversion methods that use `into_` for `Copy`
types to use `to_`.
`self` and the referenced type returned by `as_inner` are both `Copy`
types. There is no need to provide an reference getter method to a
`Copy` type since implementing `Copy` implies that copying is cheap.
We implement `source` for all our error types. This means that we should
not display the source error explicitly because users can call `source`
to get the source error.
However, `std::Error::source()` is only available for "std" builds, so
that we do not loose the error source information in "no-std" builds add
a macro that conditionally adds the source onto the error message.
Features activating external crates are supposed to have same name as
those crates. However we depend on same feature in other crates so we
need a separate feature. After MSRV bump it is possible to rename the
crates and features so we can now fix this inconsistency.
Sadly, derive can't see that the crate was renamed so all derives must
be told to use the other one.
Currently we allow multiple trailing colons when matching within the
`check_format_non_negative` macro. We can be more restrictive with no
loss of usability.
Use `$(;)?` instead of `$(;)*` to match against 0 or 1 semi-colons
instead of 0 or more.

07c75304d2 Refactor address byte swapping (Tobin C. Harding)
Pull request description:
Refactor address byte swapping
When encoding a `network::Address` two of the fields are encoded
big-endian instead of little-endian as is done by `consensus_encode`. In
order to achieve this we have a helper function `addr_to_be` that swaps
the bytes. This function is miss-named because it is not converting to a
specific endian-ness (which implies different behaviour on machines with
different endian-ness) but is reversing the byte order irrespective of
the underlying architecture.
- Remove function `addr_to_be`
- Inline the endian-ness code when encoding an address
- Remove TODO and use `to_be_bytes` when encoding port
- Add a function for reading big-endian bytes `read_be_address`
- Use `read_be_address` when decoding `Address` and `Addrv2`
Refactor only, no logic changes. Code path is already covered by
unit tests.

The chain hash for the main Bitcoin network can be verified from LN
docs (BOLT 0), add a link to this document.
Since commit `commit 275adc6c335a4326699cfbd444949e1725864ea1` on
`bitcoin_hashes` we have the identical implementation of the macro
`sha256t1_hash_newtype` in this crate and in `bitcoin_hashes`.
Remove the `sha256t_hash_newtype` macro from this crate in favour of the
one in `bitcoin_hashes`.
Clippy emits warning:
public documentation for `script_leaves` links to private item `TapTreeIter`
I'm not exactly sure why this is but adding the generic type place
holder clears the warning.
Improve documentation in `psbt/mod.rs` by doing:
- Use full sentences (full stops and capitalisation)
- Use 100 line column width
- Use back ticks and links as appropriate
- Use `Errors` section
- Use third person tense to describe functions
Improve the rustdoc documentation in the `sighash` module by doing:
- Improve grammar
- Use full sentences (full stops and capitalisation)
- Use 100 line column width
- Use back ticks and links as appropriate
- Improve correctness of `SigHashCache::new` function

No manual changes made. The result of the command above is just to fix
all the use statements (add `crate::`) and fix the fully qualified path
formats i.e., `::Foo` -> `crate::Foo`.
We do this all over the place in rust-lightning, and its probably
the most common thing to do with a `Witness` so I figured I'd
upstream the util method to do this. It also avoids an allocation
compared to the naive approach of `SerializedSignature.to_vec()`
with two pushes, which is nice.
4f1200d629 Added `amount::Display` - configurable formatting (Martin Habovstiak)
Pull request description:
This significatnly refactors the formatting code to make formatting more
configurable. The main addition is the `Display` type which is a
builder that can configure denomination or other things (possibly more
in the future).
Further, this makes all representations of numbers minimal by default,
so should be documented as a possibly-breaking change.
Because of the effort to support all other `fmt::Formatter` options this
required practically complete rewrite of `fmt_satoshi_in`. As a
byproduct I took the opportunity of removing one allocation from there.

Pull request description:
This refactors `blockdata::script::Instructions` to use

the intention and to avoid some slicing mistakes. Similarly to a
previous change this uses a macro to deduplicate the common logic and
the new `read_uint_iter` internal function to automatically advance the
iterator.

7854bd7918 Fix `no_std` MSRV Fixes#690, #947 (mcroad)
Pull request description:
`rust-bitcoin` does not work with rust 1.29 under a `no_std` environment. This could be considered a bug. However, `no_std` support is a recent addition and this is likely not breaking anyone's builds.
A decision needs to be made, either `no_std` MSRV is the current stable version while keeping the `std` MSRV as 1.29, or it needs to be fixed.
This pr adds `no_std` to the 1.29 test suite.
This came as I try to get rust-bitcoin/rust-miniscript#277 working and got stuck on the issue of testing `no_std` under 1.29.

It is more typical in this repo to use `module::Error` instead of a type
alias when importing.
Use `hex::Error` directly instead of `use hex::Error as HexError`.
d882b68a2c Add Script conversion method p2wpkh_script_code (Tobin Harding)
Pull request description:
In order to sign a utxo that does a p2wpkh spend we need to create the

The script is the same as a p2pkh script but the pubkey_hash is found in

Add a `Script` conversion method that checks if `self` is a v0 p2wpkh
script and if so extracts the pubkey_hash and returns the required
script.

548725c5fb test: reject message (de)serialization (0xb10c)
fc572aba86 fix: use var_str in 'reject' msgs (0xb10c)
Pull request description:
[BIP-61 defines `response-to-msg`][bip61] (`Reject::message` in rust-bitcoin; the message that triggered the reject) to be a `var_str`. However, by using the `CommandString` it was (de)serialized as 12 byte string. A test is added that de- and serializes two reject messages received from an older Bitcoin Core peer.
Reject message sending has been removed from Bitcoin Core, I'm still receiving them from older peers from time to time.

This creates a few primitive functions for handling iterators and uses
them to avoid repeated code. As a result not only is the code simpler
but also fixes a forgotten bound check. Thanks to a helper function
which always does bounds check correctly this can no longer be
forgotten.
This refactors `blockdata::script::Instructions` to use
`::core::slice::Iter<'a, u8>` instead of `&'a [u8]` to better express
the intention and to avoid some slicing mistakes. Similarly to a
previous change this uses a macro to deduplicate the common logic and
the new `read_uint_iter` internal function to automatically advance the
iterator.

In the future, TapTree may iterate over different node types, and that's why it does not have `iter()` function; using instead `script_leafs`. Thus, we should not have IntoIterator implementation as well
Previously used depth and script tuple missed information about the leaf version.
All three comprises already existing type `LeafInfo` which was made public in
previous commits.
