Trait LexerData 

pub trait LexerData {
    type LexerMode: LexerMode;
    type LexerRule: LexerRule;

    // Required methods
    fn start_mode() -> Self::LexerMode;
    fn dfa_bytes() -> &'static [u8] ;
    fn lookup(mode: Self::LexerMode, pattern_id: usize) -> Self::LexerRule;

    // Provided method
    fn dfa_offsets() -> &'static [usize] { ... }
}

Defines the data and configuration used by a lexer. Provides access to lexer modes, rules, DFA data, and lookup utilities.

The struct implementing this trait is automatically generated by parlex-gen’s lexer generator Alex.

Required Associated Types

type LexerMode: LexerMode

The mode type used by the lexer.

type LexerRule: LexerRule

The rule type used by the lexer.

Required Methods

fn start_mode() -> Self::LexerMode

Returns the starting lexer mode.

fn dfa_bytes() -> &'static [u8]

Returns the DFA state transition data as raw bytes.

fn lookup(mode: Self::LexerMode, pattern_id: usize) -> Self::LexerRule

Maps a mode and pattern ID to a lexer rule.

Provided Methods

fn dfa_offsets() -> &'static [usize]

Returns optional DFA offset data.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
