const it!
This crate provides some utilities for use in const evaluation contexts, in particular const slice and error handling.
The slice! and try_slice! macros slice (using any usize or range expression):
const STR: &str = slice!("const slice", ..5); // "const"
The slice_split_at! and slice_try_split_at! macros split a slice in two:
const STR: (&str, &str) = slice_split_at!("const slice", 5); // ("const", " slice")
The slice_cmp! and slice_eq! macros compare slices. slice_starts_with! and
slice_strip_prefix! checks for and strips a prefix, respectively, and
slice_ends_with! and slice_strip_suffix! do the same for suffixes.
The [ok!], expect_ok!, unwrap_ok!, unwrap_ok_or_return!, expect_some!, unwrap_some!
and unwrap_some_or_return! macros work with Results and Options.
