Trait Token

pub trait Token: Display {
    // Required methods
    fn variant_name(&self) -> &'static str;

}

Trait to implement for a token to be used with lang_util’s infrastructure

Required Methods

fn variant_name(&self) -> &'static str

Return the variant name of the current token

fn parser_token(&self) -> &'static str

Return the name used by the lalrpop parser for this token

fn kinds(&self) -> &'static [&'static str]

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.
