pub fn split_once(to_split: &[u8], by: u8) -> (&[u8], Option<&[u8]>)Expand description
Find the index of the first item by, and return a tuple of two mutable string slices
The first being the slice content up to the first instance of item by, and the second being
the slice content after the first instance of by.
This exists because there is no stable split_once for u8 slices
