Struct ByteIndex 

pub struct ByteIndex(pub usize);

A byte offset into a UTF-8 string.

This is what you use to slice a str (e.g. &text[range.start.0..range.end.0]). Not to be confused with CharIndex, which counts characters instead of bytes.

Tuple Fields

0: usize

Implementations

impl ByteIndex

pub const ZERO: ByteIndex

pub fn saturating_add(self, rhs: usize) -> ByteIndex

Saturating integer addition.

pub fn saturating_sub(self, rhs: usize) -> ByteIndex
