Crate lexe_std

Expand description

§`lexe-std`

This crate contains “std extensions” which other Lexe crates can use without having to pull in any dependencies.

Traits, macros, copies of unstable std APIs, a small number of types, are all fair game so long as they do NOT depend on anything outside of std.

array: [u8; N] array functions. Small helper functions for [u8; N] arrays.
backoff: Exponential backoff.
const_utils: Utilities for use in const fns and expressions. Utilities for use in const fns and expressions.
fmt: fmt extensions.
iter: Iterator extensions.
path: Path extensions.
string: String utilities. String utilities.

const_assert: Assert at compile that that a boolean expression evaluates to true. Implementation copied from the static_assertions crate.
const_assert_mem_size: Assert at compile time that a type has a specific in-memory size in bytes.
const_assert_usize_eq: Assert at compile time that two usize values are equal. This assert has a nice benefit where there compiler error will actually print out the two values.
const_concat_bytes: Easily concatenate multiple const &[u8] slices into a single const &[u8].
const_concat_str: Easily concatenate multiple const &str slices into a single const &str.

Apply: A trait which allows us to apply functions (including tuple enum variants) to non-Iterator/Result/Option values for cleaner iterator-like chains. It exposes an apply method and is implemented for all T.
