Pure Rust implementation of Base16 (RFC 4648).
Implements lower and upper case Base16 variants without data-dependent branches or lookup tables, thereby providing portable “best effort” constant-time operation.
Supports no_std environments and avoids heap allocations in the core API (but also provides optional alloc support for convenience).
This crate requires Rust 1.60 at a minimum.
We may change the MSRV in the future, but it will be accompanied by a minor version bump.
