Struct rec::Pattern

pub struct Pattern { /* private fields */ }

Represents a regular expression to be matched against a target.

Implementations

impl Pattern

pub fn define(rec: Rec) -> Pattern

Creates a Pattern from a Rec.

This is only safe to use with Recs that are known prior to runtime.

Panics

Panics if rec contains an invalid expression.

pub fn tokenize<'t>(&self, target: &'t str) -> Tokens<'t>

Produces Tokens that match self with given target.

pub fn tokenize_iter<'r, 't>(&'r self, target: &'t str) -> TokensIter<'r, 't>

Produces an Iterator of Tokens that match self with given target.

After each Tokens is produced, the next one is searched from the target after the current match.
