kevy-bytes 1.17.0

//! Trait impls for [`SmallBytes`] that only need the public byte-slice
//! view (`as_slice()`). The discriminator-aware `PartialEq` / `Eq` stay
//! in `lib.rs` next to the union definition because they reach into
//! `self.inline` / `self.heap` directly for the same-variant fast paths.
