Struct Lextoken

Source 
pub struct Lextoken<AT: Default> {
    pub sym: String,
    pub value: AT,
}
Expand description

This structure is deprecated by TerminalToken and is only available when installed with the legacy-parser feature. The structure is expected to be returned by the lexical analyzer (Lexer objects). Furthermore, the .sym field of a Lextoken must match the name of a terminal symbol specified in the grammar.
