Crate hybrid_array

RustCrypto: Hybrid Const Generic / Typenum Arrays

Hybrid array type combining const generics with the expressiveness of typenum-based constraints, providing an alternative to generic-array and a incremental transition path to const generics.

Documentation

About

This crate uses typenum to enable the following features which aren’t yet possible with the stable implementation of const generics:

• #60551: Associated constants in traits can not be used in const generics
• #76560: Complex generic constants: feature(generic_const_exprs)

Internally the crate is built on const generics and provides traits which make it possible to convert between const generic types and typenum types.

Features

This crate exposes the following feature flags. The default is NO features.

• zeroize - Implements Zeroize for Array<T: Zeroize, U>

Re-exports

• pub use typenum;

Modules

• consts
  Type aliases for many constants.

Structs

• Array
  Hybrid typenum-based and const generic array type.

Traits

• ArrayExt
  Extension trait with helper functions for core arrays.
• ArrayOps
  Array operations which are const generic over a given array size.
• ArraySize
  Trait which associates a usize size and ArrayType with a typenum-provided Unsigned integer.
• IntoArray
  Convert the given type into an Array.

Functions

• slice_as_chunks
  Splits the shared slice into a slice of N-element arrays, starting at the beginning of the slice, and a remainder slice with length strictly less than N.
• slice_as_chunks_mut
  Splits the exclusive slice into a slice of N-element arrays, starting at the beginning of the slice, and a remainder slice with length strictly less than N.
