Function bytes_strip_prefix

pub const fn bytes_strip_prefix<'a, const N: usize, P>(
    left: &'a [u8],
    prefix: &P,
) -> Option<&'a [u8]>
where
    P: ?Sized + BytesPattern<N>,

Remove prefix from the start of left.

Returns None if prefix is not the start of left.

This is analogous to <[u8]>::strip_prefix

Example

use konst::slice::bytes_strip_prefix;

assert_eq!(bytes_strip_prefix(b"foo,bar,baz", b"foo,"), Some("bar,baz".as_bytes()));
assert_eq!(bytes_strip_prefix(b"foo,bar,baz", "foo,bar,"), Some("baz".as_bytes()));
assert_eq!(bytes_strip_prefix(b"foo,bar,baz", &'f'), Some("oo,bar,baz".as_bytes()));

assert_eq!(bytes_strip_prefix(b"foo,bar,baz", b"bar"), None);
assert_eq!(bytes_strip_prefix(b"foo,bar,baz", b"baz"), None);
