pub const fn bytes_find<const N: usize, P>(
left: &[u8],
pattern: &P,
) -> Option<usize>where
P: ?Sized + BytesPattern<N>,
Expand description
Finds the byte offset of pattern
in left
.
Returns None
if pattern
isn’t inside left
§Example
use konst::slice::bytes_find;
assert_eq!(bytes_find(b"foo-bar-baz", &'q'), None);
assert_eq!(bytes_find(b"foo-bar-baz", "foo"), Some(0));
assert_eq!(bytes_find(b"foo-bar-baz", b"bar"), Some(4));
assert_eq!(bytes_find(b"foo-bar-baz", b"baz"), Some(8));
