Trait FromLexError 

pub trait FromLexError<'a, T, S> {
    // Required method
    fn from_lex_error(err: <T::Logos as Logos<'a>>::Error, span: S) -> Self
       where T: Token<'a>;
}

A trait for converting a lexer error into the target error.

Required Methods

fn from_lex_error(err: <T::Logos as Logos<'a>>::Error, span: S) -> Self

where T: Token<'a>,

Converts a lexer error into the target error with the span

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.
