Struct hime_redist::lexers::automaton::AutomatonState

pub struct AutomatonState<'a> { /* private fields */ }

Represents a state in the automaton of a lexer Binary data structure: u16: number of matched terminals u16: total number of transitions u16: number of non-cached transitions – matched terminals u16: context identifier u16: index of the matched terminal – cache: 256 entries u16: next state’s index for index of the entry – transitions each transition is of the form: u16: start of the range u16: end of the range u16: next state’s index

Implementations

impl<'a> AutomatonState<'a>

pub fn get_terminals_count(&self) -> usize

Gets the number of matched terminals in this state

pub fn get_terminal(&self, index: usize) -> MatchedTerminal

Gets the i-th matched terminal in this state

pub fn is_dead_end(&self) -> bool

Gets whether this state is a dead end (no more transition)

pub fn get_bulk_transitions_count(&self) -> usize

Gets the number of non-cached transitions in this state

pub fn get_cached_transition(&self, value: Utf16C) -> u32

Gets the target of the cached transition for the specified value

pub fn get_bulk_transition(&self, index: usize) -> AutomatonTransition

Gets the i-th non-cached transition in this state

pub fn get_target_by(&self, value: Utf16C) -> u32

Gets the target of a transition from this state on the specified value
