A Rust hexadecimal decoding library
General purpose hex encoding/decoding library with a conservative MSRV and dependency policy.
Stabilization strategy
Because downstream crates may need to return hex errors in their APIs and they need to be stabilized soon, this crate only exposes the errors and two basic decoding functions. This should already help with the vast majority of the cases and we're sufficiently confident that these errors won't have a breaking change any time soon (possibly never).
If you're writing a binary you don't need to worry about any of this and just use the unstable version for now. If you're writing a library you should use these stable errors in the API but you may internally depend on the unstable crate version to get the advanced features that won't affect your API. This way your API can stabilize before all features in this crate are fully stable and you still can use all of them.
Crate feature flags
std
- enables the standard library, on by default.alloc
- enables features that require allocation such as decoding intoVec<u8>
, implied bystd
.newer-rust-version
- enables Rust version detection and thus newer features, may add dependency on a feature detection crate to reduce compile times. This feature is expected to do nothing once the native detection is in Rust and our MSRV is at least that version. We may also remove the feature gate in 2.0 with semver trick once that happens.
Minimum Supported Rust Version (MSRV)
This library should compile with almost any combination of features on Rust 1.63.0, however we
reserve the right to use features to guard compiler specific code so --all-features
may not work
using the MSRV toolchain.
Policy
We don't intend to bump MSRV until the newer Rust version is at least two years old and also included in Debian stable (1.63 is in Debian 12 at the moment).
Note though that the dependencies may have looser policy. This is not considered
breaking/wrong - you would just need to pin them in Cargo.lock
(not .toml
).
Githooks
To assist devs in catching errors before running CI we provide some githooks. If you do not already have locally configured githooks you can use the ones in this repository by running, in the root directory of the repository:
git config --local core.hooksPath githooks/
Alternatively add symlinks in your .git/hooks
directory to any of the githooks we provide.
