In a few places in the codebase we want to grab an reference to an input
by index. To reduce code duplication add two methods on `Transaction`,
each to get a reference to an input or output respectively.
These are public methods, do not use them yet internally.
Currently we loop over transaction inputs within a loop over transaction
inputs - ouch.
Cache the `use_segwit_serialization` outside the iteration loop.

aa6e5cd342 Use full path in all macro usage of Result (Steven Roose)

Our decoding code reads bytes in very small chunks. Which is not
efficient when dealing with the OS where the cost of a context switch is
significant. People could already buffer the data but it's easy to
forget it by accident.
This change requires the new `io::BufRead` trait instead of `io::Read`
in all bounds.
Code such as `Transaction::consensus_decode(&mut File::open(foo))` will
break after this is applied, uncovering the inefficiency.
This was originally Kix's work, done before we had the `io` crate.
Changes to `bitcoin` were originally his, any new mistakes are my own.
Changes to `io` are mine.

518f0970c9 Implement ArbitaryOrd for absolute::LockTime (Tobin C. Harding)
Pull request description:
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.

Applies to both `ecdsa::Signature` and `taproot::Signature`.
Re-name the `Signature` fields with more descriptive names. The
names used were decided upon in the issue discussion.
Impove rustdocs while we are at it.
Note, the change to `sign-tx-segwit-v0` is refactor only, the diff does
not show it but we have a local variable already called `sighash_type`
that is equal to `EcdsaSighashType::All`.
Includes a function argument rename as well, just to be uniform.

The `as_unchecked` method is never dangerous to call because an
`Address<UncheckedNetwork>` provides a subset of functionality that is
always ok to use. It is only dangerous to go the other way unchecked to
checked.
This lint triggers on `fn input_len(&self) -> usize { match *self {} }`
where Self is an infallible type, claiming that the dereference of self
is UB. Maybe it would be, if this were possible. But it's not, and this
is literally the only point of using infallible types, so this lint is
always wrong.
Enabled in rustc 1.76 as warn by default.
This method is not really that useful because it checked an arbitrary
condition. There already exists `OP_RETURN` semantics and the method
didn't cover all possible ways the script may be invalid.
This deprecates the method and documents why.

BIP-32 only differentiates between mainnet and some testnet when
encoding and decoding xpubs and xprivs. As such we can use the new
`NetworkKind` type instead of `Network` throughout the `bip32` module.
We only use the network to serialize and deserialize from WIF.
For this we only really need network kind since WIF only differentiates
between mainnet and non-mainnet.
Add a new type `NetworkKind` the describes the kind of network we are
on, ether mainnet or one of the test nets (testnet, regtest, signet).
Do not use the type yet.

The `bitcoinconsensus` crate is not fully under our control because it
exposes code from Core, so we cannot guarantee its stability across
versions. To make our semver compliance easier we can fully encapsulate
the `bitcoinconsensus` crate so it does not appear in our public API.
However, it is useful to have the crate itself exported, here we add an
"unstable" feature and only publicly export the `bitcoinconsensus` crate
if the "unstable" feature is enabled.
P2WPKH requires keys to be compressed which introduces error handling
even in cases when it's statically known that a key is compressed. To

There is no advantage in having `io::Read` as opposed to `Read` and
importing the trait. It is surprising that we do so.
Remove `io::` path from `io::Read` and `io::Write`. Some docs keep the
path, leave them as is. Add import `use io::{Read, Write}`.
Refactor only, no logic changes.
When we use the `fmt::Write` trait it is just to call its methods, we
can therefore, without any change to the logic, use `as _` when
importing the trait. This prevents naming conflicts.
Done in preparation for importing the `io::Write` trait.
Generic types can be single letters, and a writer is conventionally, in
this codebase at least, called `W`.
Use `W` instead of `Write` with no loss of clarity.

1. The dust amount depends on minrelaytxfee which is configurable in Bitcoin Core. This method was not configurable.
2. The division operation was done before multiplying the byte amount, which can cause small differences when using uncommon scripts and minrelaytxfee values.

there can never happen. I made this explicit by manually setting the
parity.
This is a rebase of Steven's change with a rewrite of `match` to not
panic.
Since the iterator created by `IntoIterator` should be called `IntoIter`
we move the whole `TaprootMerkleBranch` to its own module which contains
the type to avoid confusion. This has an additional benefit of reducing
the scope where the invariant could be broken. This already uncovered
that our internal code was abusing access to the private field (although
the code was correct).
To implement the iterator we simply delegate to `vec::IntoIter`,
including overriding the default method which are likely to be
implemented by `Vec` more optimally. We avoid exposing `vec::IntoIter`
directly since we may want to change the representation (e.g. to
`ArrayVec`).
The type is naturally a collection of hashes so make it behave that way
by implementing `Deref`, `AsRef`, `Borrow` and their mutable versions as
well as `IntoIterator` for its reference. `IntoIterator` for itself is
not yet implemented because it's a bit more complicated.
While `clippy` now allows `TBD` to be used in `since` parameter of
`deprecated` attribute it is only available in the newest, nightly,
version. Switch `clippy` version to nightly to enable the `TBD` value.

dffa51e735 Move taproot module to a subdirectory (Martin Habovstiak)
Pull request description:
Previously `taproot::Signature` could be only serialized into `Vec<u8>`
which forced allocation. This adds a `SerializedSignature` type which
acts like `Box<u8>` but is on stack.
Note: the code was copied from `secp256k1::ecdsa::serialized_signature`
with minimal changes.

Add a feature matrix section to the `bitcoin` CI script as we do in
`hashes`. This means:
- test with no default features
- test with all individual features
- test with all combinations of two features
Note, with this applied all features and optional dependencies are
included in `FEATURES` (excluding `secp-lowmemory`).
The feature matrix test gets run for stable and MSRV toolchains.
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.
We are emptying the `hash_types` module. `impl_asref_push_bytes!` is an
internal macro, as such it can live in the `internal_macros` module.
While we are at it import the macro and call it without any qualifying
path, this is typical for our usage of other internals/internal_macros
usage.
We would like all the various hash types to be defined where they
rightly live instead of in the `hash_types` module.
Move the BIP-158 filter hash types to the `bip158` module.
We would like all the various hash types to be defined where they
rightly live instead of in the `hash_types` module.
Move transaction hash types to the `transaction` module.
We would like all the various hash types to be defined where they

Move the block hash types to the `block` module. While moving, add full
stops to the rustdoc of each hash.
Re-export _all four_ types from lib.rs (previously `WitnessMerkleNode`
was not re-exported).
An `AddressInner` struct is created when parsing address strings however
address strings do not map 1:1 to `Network` because signet and testnet
use the same bech32 prefix "tb".
We can fix this by inlining the `Payload` variants into `AddressInner`
and adding prefix enums for legacy addresses and a `KnownHrp` for bech32
addresses.
Also enables removing the `AddressEncoding` struct as we can display the
`AddressInner` struct directly. (The `Display` impl is on `AddressInner`
and not directly on address to ignore the `NetworkValidation` wrapper,
may be able to be simplified still further.)
Calling `wpubkey_hash` on a key that is uncompressed is flat out an
error, really it is a programmer error at build time because a segwit
key should never be compressed, however, for historical reasons we do
not enforce this in the type system. As a step towards clarity make it
an error to call `wpubkey_hash` on a an uncompressed pubkey. This adds
documentation and potentially might assist debugging for newer devs.
