We have a bunch of `from_<key>` methods for converting between key types.
To improve the API and make it more ergonomic to use we can add methods
that do the same but can be called on the initial key instead of on the
resulting key's type. E.g. once applied the following are equivalent:
- `let pk = PublicKey::from_keypair(kp)`
- `let pk = kp.public_key()`
Do this for `SecretKey`, `PublicKey`, `KeyPair`, and `XOnlyKeyPair`.
Recently we moved from using the identifier 'schnorrsig' to 'schnorr',
we omitted to update the tests.
While we are at it use more idiomatic Rust unit test names (i.e., do not
start test name with `test_` because it stutters when the name is read
in output of `cargo test`).
Recently we moved from using the identifier 'schnorrsig' to 'schnorr',
we omitted to update the schnorr signature size constant.
Deprecate `SCHNORRSIG_SIGNATURE_SIZE` and add
`SCHONORR_SIGNATURE_SIZE`.
Recently we moved from using the identifier 'schnorrsig' to 'schnorr',
we omitted to update the schnorr public key size constant.
Deprecate `SCHNORRSIG_PUBLIC_KEY_SIZE` and add
`SCHONORR_PUBLIC_KEY_SIZE`.
We are using `cfg_attr` to instruct the rustdocs build system to
highlight feature requirements for functions, there is no need to
explicitly mention feature requirements in the text.
Recently we fixed a bunch of feature gates to use `rand-std` instead
of `rand` but in doing so did not notice that the same feature gates
were using `alloc` which is meaningless if `std` is enabled.
Feature gate on `std` if we are using `rand-std`.
Our API often involves a `Secp256k1` parameter, when users enable the
`global-context` feature they must then pass `SECP256K1` into these
functions. This is kind of clunky since the global is by definition
available everywhere.
Make the API more ergonomic for `global-context` builds by adding
various API functions/methods that use the global context implicitly.
Various combinations of features trigger lint warnings for unused code,
all warnings are caused by incorrect feature gating.
Correct feature gating to remove Clippy warnings during testing.
Currently various features fail to build when enabled without default
features. This is because many tests need feature gating.
Feature gating the import statements quickly turns into spaghetti when
trying to cover all combinations of two features correctly, instead just
allow unused imports on `tests` modules where needed.
Add correct feature requirements to the examples so they also can be run
without default features.
Improve the CI script by doing:
- Add `std` to the feature matrix.
- Add `--no-default-features` to test runs in the CI script.
We have deprecated all other functions that use the identifier
'schnorrsig' but we missed `generate_schnorrsig_keypair`.
This function is purely a helper function and serves no real purpose
other than to reduce two lines of code to a single line. Downstream
users can write this function themselves if they need it.
Also, we recently added a new public method to `KeyPair` to get the
public key in a slightly more ergonomic fashion. Use `kp.public_key()`
when replacing usage of now deprecated `generate_schnorrsig_keypair`
function.

This documents the Cargo features making sure docs.rs shows warning for
feature-gated items. They are also explicitly spelled out in the crate
documentation.
There are currently two unit tests in the `schnorr` module that are
testing keys from the `key` module. This is possible because the tests
are only testing the public interface, none the less they are better
placed in the `key` module.
- The current schnorrsig verify methods should operate on verify context
as is done throughout the bitcoin core
- Scondly, and importantly the XonlyPublicKey::from_keypair now operates
without any context objects.
