source · 
pub struct StateMachine { /* private fields */ }
Expand description

A state machine that can be used to match a regex.

Implementations§

source§

impl StateMachine

source

pub fn parse_inst( &mut self, position: usize, program: &Program ) -> Vec<(usize, Vec<StepCase>)> ⓘ

Parse a regex program into a state machine.

Panics

Panics if the program contains a [Inst::EmptyLook] instruction.

source

pub fn end_patterns(self) -> HashMap<usize, usize>

source

pub fn extend_steps( &mut self, steps: Vec<(usize, Vec<StepCase>)> ) -> Vec<(usize, Vec<StepCase>)> ⓘ
