const-slice
Compile-time constant variants of several slice types over dynamically allocated types, implemented as slices over a fixed-capacity array (controlled by const generics).
The types in this crate will panic at compile-time if they would exceed the size of their array (currently produces a very unhelpful error - see #51999)
Examples
const FIRST: &str = "mary had a";
const SECOND: &str = " little lamb.";
const BOTH: = from_str.with_str;
assert_eq!;
