This represents the first breaking change in a new release series,
bumping all crates to the 2024 edition of Rust.
As such, the version numbers of all crates have been incremented to
represent a new prerelease series:
- `curve25519-dalek`: v5.0.0-pre
- `ed25519-dalek`: v3.0.0-pre
- `x25519-dalek`: v3.0.0-pre
Note that this commit isn't intended to cut associated crate releases of
these on crates.io, but is merely bumping the version numbers to denote
there are pending breaking changes.
This commit also includes rustfmt changes which were made as part of the
2024 edition.
Also includes clippy fixes.
To avoid nightly regressions breaking the build, the CI configuration
has been updated to *only* use nightly for resolving Cargo.lock by using
`cargo update -Z minimal-versions`.
Previously, it was running `cargo check` which would attempt to compile
all of the dependencies and the code, which is why the diagnostic bug
was triggered. By avoiding any kind of code compilation using nightly we
can avoid such regressions in the future.
Additionally, the clippy job has been changed to run on the latest
stable release (1.73.0) rather than nightly, which will prevent future
clippy lints from breaking the build. Instead, they can be addressed
when clippy is updated.
