Struct Memo 

pub struct Memo {
    pub start: usize,
    pub end: usize,
    pub aux: usize,
}

Per-line, per-finder scratch handed to Finder::try_at_memo/Finder::try_trigger_at_memo.

A finder may record what it learned about the current line (typically the extent of a run that cannot match) so that later attempts on the same line stay cheap. It is a cache only: results must not depend on it. The scanner resets it to Memo::default() (an empty range) for every line.

Fields

start: usize

end: usize

aux: usize

Free slot for one more position the finder wants to remember.

Implementations
