bounded-vec

BoundedVec<T, L, U> - Non-empty rust std::vec::Vec wrapper with type guarantees on lower(L) and upper(U) bounds for items quantity. Inspired by vec1.

This crate is #![no_std] compatible with alloc.

Example

use bounded_vec::BoundedVec;

let data: BoundedVec<u8, 2, 4> = [1u8,2].into();

assert_eq!(*data.first(), 1);
assert_eq!(*data.last(), 2);

// creates a new BoundedVec by mapping each element
let data = data.mapped(|x|x*2);
assert_eq!(data, [2u8,4].into());

Crate features

• optional(non-default) serde feature that adds serialization to BoundedVec.
• optional(non-default) schema feature that adds JSON schema support via schemars (requires serde).
• optional(non-default) arbitrary feature that adds proptest::Arbitrary implementation to BoundedVec.
