Struct LexerPredicate 

pub struct LexerPredicate { /* private fields */ }

Grammar-specific lexer predicate reached while exploring an ATN path.

Implementations

impl LexerPredicate

pub const fn new(rule_index: usize, pred_index: usize, position: usize) -> Self

Creates a lexer predicate event from serialized ATN metadata.

pub const fn rule_index(self) -> usize

Lexer rule index that owns the predicate transition.

pub const fn pred_index(self) -> usize

Per-rule predicate index assigned by ANTLR serialization.

pub const fn position(self) -> usize

Character-stream position at which the predicate is evaluated.

Trait Implementations

impl Clone for LexerPredicate

fn clone(&self) -> LexerPredicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LexerPredicate

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

Formats the value using the given formatter.

impl PartialEq for LexerPredicate

fn eq(&self, other: &LexerPredicate) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
