Trait scan_rules::input::SkipSpace

pub trait SkipSpace: 'static {
    fn match_spaces(a: &str, b: &str) -> Result<(usize, usize), usize>;
    fn skip_space(a: &str) -> usize;
}

Defines an interface for skipping whitespace.

Required Methods

fn match_spaces(a: &str, b: &str) -> Result<(usize, usize), usize>

Given two strings, does the leading whitespace match?

If so, how many leading bytes from each should be dropped?

If not, after many bytes into a do they disagree?

fn skip_space(a: &str) -> usize

Return the number of bytes of leading whitespace in a that should be skipped.
