Struct regex_automata::hybrid::dfa::SearchProgress

struct SearchProgress {
    start: usize,
    at: usize,
}

Keeps track of the progress of the current search.

This is updated via the Cache::search_{start,update,finish} APIs to record how many bytes have been searched. This permits computing a heuristic that represents the efficiency of a cache, and thus helps inform whether the lazy DFA should give up or not.

Fields

start: usize

at: usize

Implementations

impl SearchProgress

fn len(&self) -> usize

Returns the length, in bytes, of this search so far.

This automatically handles the case of a reverse search, where at is likely to be less than start.

Trait Implementations

impl Clone for SearchProgress

fn clone(&self) -> SearchProgress

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SearchProgress

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

Formats the value using the given formatter.
