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.
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.
It could happen that we unknowingly depend on a new version of a crate
without updating `Cargo.toml`. This could cause resolution issues for
downstream users. It's also unclear for outsiders to see which
dependencies we tested the crate with.
This change commits two lock files: `minimal` and `recent`. `minimal`
contains minimal depdendency versions, while `recent` contains
dependency versions at the time of making the change.
Further, this adds CI jobs to test with both lock files, CI job for
`internals` crate, removes old `serde` pinning and prints a warning if
`recent` is no longer up to date. (We may have to override it somehow if
any crate breaks MSRV.)
The documentation is also updated accordingly.

Closes#1230
Done as is single patch to make sure all the docs and CI are in sync and
correct.
We currently pin the `schemars` dependency using `<=0.8.3` as well as a
the `dyn-clone` transient dependency in the manifest (`hashes` and the
extended test crate). This is incorrect because it makes usage of the
crate klunky (or possibly impossible) if downstream users wish to use a
later version of `schemars`.
Observe also that we do not have to pin `schemars`, we do however have to pin
the `serde` crate if either `serde` or `schemars` features are enabled.
Do so in CI and document in the readme file within hashes.
Currently we have a pin remaining from the old MSRV (`syn` due to use
of `matches!`).
Fix pinning by:
- Remove pin in manifest for `schemars`
- Fix pinning for MSRV in CI and docs (this includes documenting pinning
requirements for `schemars` feature because it is related to the other
pin of `serde`) in both `hashes` readme and main repo readme.
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.
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.
Run docs in CI using nightly and stable toolchains as required.
In order to get better test coverage we should not enable the secp26k1
feature "rand-std" in dev-dependencies but instead feature gate tests
that depend on this feature.
Convert all rustdocs build warnings to errors using `-D warnings` and
exit the script with 1 to signal the error.
While we are at it use `--all-features` instead of explicit feature list
when building docs. Without this the docs build fails with:
error: too many file operands
1a89d5230c examples: Add taproot-psbt workflow example (Duncan Dean)
Pull request description:
Will address #893.
Currently includes a BIP86 example (no spendable script path)
Working on script path and key path spending when both are possible spending paths.

This example shows how to use the PSBT API for taproot transactions.
We have a simple BIP86-style spend and an example of an inheritance
timelock that can be spent either by the beneficiary via the script
path after a timelock, or via the key path by the benefactor so that
they can refresh the timelock at any time.
Create a directory `bitcoin` and move into it the following as is with
no code changes:
- src
- Cargo.toml
- contrib
- test_data
- examples
Then do:
- Add a workspace to the repository root directory.
- Add the newly created `bitcoin` crate to the workspace.
- Exclude `fuzz` and `embedded` crates from the workspace.
- Add a contrib/test.sh script that runs contrib/test.sh in each
sub-crate
- Fix the bitcoin/contrib/test.sh script
