Struct Matches

Source

pub struct Matches { /* private fields */ }

Expand description

A collection of matches produced by a rule. The user can choose which matches to be fired.

Implementations§

Source §

impl Matches

Source

pub fn match_size(&self) -> usize

The number of matches in total.

Source

pub fn tuple_len(&self) -> usize

The length of a tuple.

Source

pub fn get_match(&self, idx: usize) -> Match<'_>

Get idx-th match.

Source

pub fn choose(&mut self, idx: usize)

Pick the match at idx to be fired.

Source

pub fn choose_all(&mut self)

Pick all matches to be fired.

This is more efficient than calling choose for each match.
