Trait Storable

pub trait Storable<W: Word>: Sized + Copy {
    // Required methods
    fn into_word(self) -> W;
    fn from_word(word: W) -> Self;
}

A trait that defines a bidirectional, lossless conversion between a user-facing element type T and its storage representation W.

This trait is central to FixedVec’s ability to store various integer types in a generic bit buffer.

Required Methods

fn into_word(self) -> W

Converts the element into its storage word representation.

For signed integers, this conversion uses ZigZag encoding to map negative and positive values to a compact unsigned representation.

fn from_word(word: W) -> Self

Converts a storage word representation back into an element.

For signed integers, this reverses the ZigZag encoding.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
