Recently we made an attempt at making the hex APIs for scripts easier to
use, better documented, and shown via an example.
After that work we decided it would be better if `LowerHex`/`UpperHex`
did not have the prefix. We also wanted to further clarify the inherent
function names to make the all explicit.
See GitHub issue #4316 for the thread of discussion.
Note that this PR does not require changes to the serde regression test
which were non changed in the original work either.
Name the type exactly what it is. This used to be `Time`, then we tried
`MtpInterval`.
Note that this makes some of the original function names overly verbose
e.g., `NumberOf512seconds::from_512_second_intervals()` but given the
curlyness of locktimes too verbose is better than too terse. Also this
type, along with `NumberOfBlocks` is not going to be in very wide use so
the ergonomic hit is worth the additional clarity.
Name this type exactly what it is. Note for the error we just use
'height' even though this is a bit stale but the general concept is ok
in the error type because the name is long already.

Pull request description:
This is a more involved PR than I'd expected but hopefully the individual commits make sense and are well-motivated. Essentially, my goal was to replace `MtpAndHeight` as used by relative locktimes with a pair of `Mtp` and `Height`.
However, relative locktimes, when given a MTP/Height for the UTXO creation and the chain tip, are roughly modeled as "take a diff of MTPs to get a `relative::MtpInterval`, a diff of heights to get a `relative::HeightInterval`, and compare to the locktimes". *However*, we have no standalone MTP type to "take a diff of", and also there are failure modes when creating the diffs (e.g. if the diff would exceed the range of `MtpInterval` or `HeightInterval`).
So I backed up and decided to use the existing `BlockHeight`/`BlockInterval` as the type to "take a diff of". I needed to introduce a `BlockMtp`/`BlockMtpInterval` to work with MTPs. These types have full-u32 range, unlike the similarly-named types in `units::locktimes::absolute`. I then needed to add some conversion methods. Along the way, I cleaned up the APIs and documentation, added checked arithmetic, etc., as needed.
See the individual commit messages for more detail.
I believe the resulting API is much more consistent and discoverable, even though it has more surface than the old API.
I considered splitting this into 2 PRs but I think the first half of the changes aren't well-motivated with out the second half. Let me know.

2a518d62e6 Wrap secp256k1::XOnlyPublicKey to improve error handling (Erick Cestari)
Pull request description:
This PR addresses issue #4361 by creating a wrapper type for XOnlyPublicKey instead of directly re-exporting it from the secp256k1 library.
### Key Changes
1. Created a new `XOnlyPublicKey` struct that wraps `secp256k1::XOnlyPublicKey`
2. Implemented custom error types:
- `ParseXOnlyPublicKeyError` for handling parsing errors
- `TweakXOnlyPublicKeyError` for tweaking an `XOnlyPublicKey`
3. Updated all imports and usage throughout the codebase
4. Implemented necessary traits and methods for compatibility

There is a new lint error on nightly-2025-04-25 "variables can be used directly in the `format!` string".
The existing syntax `format!("{}", x)` is more commonly used than `format!("{x}")` therefore allow it in existing code.
Also the rustdoc example in #4259 now causes the new nightly to fail CI because of the unused variable.
Patches in the PR:
- Exclude the lint to allow the existing syntax in `format!` strings in all crate `lib.rs`, `build.rs.` and test files.
- Use the variables in the `format!` string for all cases in `bitcoin/examples/` since there are no other allowed lints in examples.
- Correct the function names in the rustdoc example and prefix the unused variable with an underscore.
- Update rustc to nightly-2025-05-02 (2025-04-25 had a bug which is fixed in 2025-05-02).

For our relative locktime API, we are going to want to take differences
of arbitrary MTPs in order to check whether they meet some relative
timelock threshold.
However, the `locktime::absolute::Mtp` type can only represent MTPs that
exceed 500 million. In practice this is a non-issue; by consensus MTPs
must be monotonic and every real chain (even test chains) have initial
real MTPs well above 500 million, which as a UNIX timestamp corresponds
to November 5, 1985.
But in theory this is a big problem: if we were to treat relative MTPs
as "differences of absolute-timelock MTPs" then we will be unable to
construct relative timelocks on chains with weird timestamps (and on
legitimate chains, we'd have .unwrap()s everywhere that would be hard to
justify). But we need to treat them as a "difference of MTPs" in *some*
sense, because otherwise they'd be very hard to construct.
Refactor Taproot functions to accept any type implementing `Into<XOnlyPublicKey>`,
instead of requiring `XOnlyPublicKey` directly. This improves ergonomics when working
with compatible types, avoiding unnecessary `.into()` conversions at call sites.
There is a new lint error on nightly-2025-04-25 "variables can be used
directly in the `format!` string".
Use the variables in the `format!` string for all cases in

Pull request description:
This PR does a whole bunch of renames to the `units` locktime modules. These modules contain the underlying units for locktime types and hopefully aren't used directly too often, which should minimize the disruption from these renames.
This fixes a number of issues:
* Confusion between blocktimes and MTPs (which in fairness, *are* blocktimes, but they're not the one that users are likely to reach for)
* Constructor and conversion names that imply there is a "consensus encoding" for these bare units, which corresponded to the consensus encoding of the corresponding locktimes/sequence numbers
* `from_*` methods without `to_*` methods and vice-versa (overlaps with the above)
* the horribly named `value` method on relative heights and times (but not absolute ones)
This PR does **not** remove the `MtpAndHeight` type, nor does it add constructors for `Mtp` from lists of blocktimes. This is because the PR was too big already and I felt I should split it up.

This is disruptive, but makes the type name consistent with
`MtpInterval` and also greatly improves clarity, helping to distinguish
between absolute and relative locktimes and reminding the author (and
reviewer) of locktime code that this needs to be a diff.
This is not a generic UNIX timestamp, but rather a MTP restricted to
have values between 500 million and u32::MAX. Most importantly, it is
*not* a blocktime, which is what is implied by its name and
constructors.
For TweakedKeypair, `to_inner` is also renamed to `to_keypair` to maintain
consistency. Similarly, `to_inner` is renamed to `to_x_only_pubkey` for

Pull request description:
This PR makes a first pass at splitting the `bip32::Error` type into multiple distinct types -- one for derivation (which can fail if you try to derive a hardened child of an xpub, or if you try to derive too many layers), one for parsing child numbers or derivation paths, and one for parsing xkeys. Along the way it cleans up a ton of weird things and typos, e.g. the psbt `GetKeyError` having an unused `Bip32` variant whose display text references "bip 23".
Because all the error types get renamed, every part of this PR is an API break, but only the last commit is a "real" API break which uses the new `DerivationError::MaximumDepthExceeded` error variant to return an error when trying to derive a path of length 256 or longer. This means that `Xpriv::derive_xpriv` again returns an error result.
I will make a simpler version of this last commit suitable for backporting to 0.32.x. (In 0.32.x `Xpriv::derive_priv` returns an error, so we can change it to error out on max-depth-exceeded without breaking the API. Sadly most users are likely to be unwrapping the error because in 0.32.x currently the error path is cryptographically unreachable...but at least this way the panic will be in their control rather than ours.)

parsing and decoding. It is still a little messy (mainly: it contains a
base58 variant which is used when parsing a string but not when decoding
from bytes) but much cleaner than it was.

Add the length prefix when formatting hex strings by way of `LowerHex`
and `UpperHex`.
This looses formatting options because I can't remember right now how
not to - again.
I'm not sure why we do not use consensus encoding currently for encoding
and decoding scripts to/from hex strings. Many tests include hard coded
hex which do not include the length prefix.
- Add a pair of encoding functions to encode/decode to/from hex without
the length prefix.
- Make `to_hex` and `from_hex` expect the length prefix i.e., use
consensus encoding.
This makes the API easier to use because the various encoding APIs can
be use together now eg `consensus::encode_hex` and `ScriptBuf::from_hex`.
Our encoding/decoding support for scripts is currently a bit convoluted.
Add an example that shows how all the APIs go together.
Note this highlights a potential problem. `to_hex_string` is in
`bitcoin` and therefore has access to consensus encoding but does not
include the length prefix. This means that the output string from
`to_hex_string` cannot be parsed with
`consensus::encode::deserialize_hex` - which is surprising and has lead
to difficulty by at least one user trying to debug.

There is also a mix in the usage of `#`, `##` or `###` for headings. Noticed here https://github.com/rust-bitcoin/rust-bitcoin/pull/2792#issuecomment-2125775974.
- Fix a typo found when looking into this.
- Change all occurances to use `# Parameters` in rustdocs.
- Change all heading levels to H1 `#`
- Change all subheading levels to H3 `###` to make the small difference in the rendered font size noticable
Closes#4380

Currently in this module we have a distinction between an "index" which
is a number between [0, 2^31 - 1] which indexes into the set of normal
or hardened child numbers. We also have a child *number*, which within
the library is an opaque type, but can be freely converted into/out of a
u32 in the consensus encoding which uses the MSB as a normal/hardened
flag and the other bits to encode the index.
Probably we want to change ChildNumber::From<u32> to some sort of
from_consensus_u32 method, but that's out of scope for this PR. What is
*in scope*, though is fixing the error types.
In the existing code we have three problems:
* Our error type for a bad index is called InvalidChildNumber, rather
than InvalidIndex, and the error message reflects this, which is wrong
and confusing. (Some with InvalidChildNumberFormat.)
* The InvalidChildNumberFormat is always constructed from a ParseIntError
from stdlib, but we always throw that away rather than preserving it.
* These two error variants only appear when parsing child numbers, or
derivation paths which are lists of child numbers, but they are part
of the main error enum.
This is a breaking change to the API of the deprecated `derive_pub`
function, but it's in a way that's unlikely to break consumers (who are
probably just .expect'ing the result) so we will retain the deprecated
function.
There was and inconsistent usage of `#`, `##` and `###` in rustdoc
headings. The difference in the rendered rustdocs is a minimal font
size change.
Change all headings to be H1 `#`.
Change all subheadings to be `###` to have a noticeable difference in
font size in the rendered docs.

354e1e42ad fix: enforce minimal push for push_slice (ChrisCho-H)
Pull request description:
Currently `push_slice` doesn't check the standard minimal push rule, which could result in possible money loss(e.g. if non minimal push is used in output script of p2wsh or p2tr).
Introduce `push_slice_non_minimal` to provide the way to push as now, and change `push_slice` logic to follow standard minimal push rule.

0498f7b7b7 Remove Option return from `minimal_non_dust` (jrakibi)
Pull request description:
Closes#4221
This removes the `Option` return type from `minimal_non_dust
Overflow is only possible in 2 cases:
- `dust_relay_fee` would need to be excessively high
- script size would have to exceed ~6.15 × 10¹⁵ bytes (≈ 6 petabytes)

a5f904559d primitives: Make hex optional (Tobin C. Harding)
Pull request description:
Make the `hex` dependency optional. This means not implementing
`Display` for some types if `hex` is not enabled and only implementing
`Debug`.
Also without `hex` enabled:
- We loose the ability to parse an `OutPoint` from string because we
can no longer parse `Txid`.
- We loose the hex formatting of witness elements.
Note also that `primitives` builds with the `serde` feature even if
`hex?/serde` is excluded from the `serde` feature. I found this
surprising.

We have the `hex_lit` dependency for converting a hex string literal
to an array.
Currently we have a `test_hex_unwrap` macro in the `hex v0.3.0` release
but not on either `master` or the upcoming `v1.0.0-alpha.0` release.
This is making PRs around releasing and depending on the release more
noisy than required.
Use `hex_lit::hex` where possible (often needing an additional call to
`to_vec()`) and where not possible use `Vec::from_hex`.
We can use `deserialize_hex` when outside of the actual benchmark code
to simplify the functions.
Also add an additional test that benchmarks `deserialize_hex`.
