pub enum Engine {
    Regex(Regex),
    Fancy(Regex),
}

Implementations

impl Engine

pub fn find_all(&self, text: &str) -> Vec<(usize, usize)>

Find all matches in text. Returns Vec<(start, end)> byte spans (within text). Allocations are minimized — caller can iterate the returned vector or pass it to the formatter.

pub fn is_match(&self, text: &str) -> bool

Quick yes/no check; used by -q, -l, -L.

Trait Implementations

impl Debug for Engine

fn fmt(&self, f: &mut Formatter<'_>) -> Result
