Trait flexi_parse::TokenLike

pub trait TokenLike {
    type TokenTypes: TokenTypes;

    // Provided methods
    fn peek(input: ParseStream<'_>) -> bool { ... }
    fn lookahead(lookahead: &Lookahead<'_>) -> bool { ... }
}

A trait for types that represent one of a few possible tokens.

This allows peeking for multiple types through the provided trait methods.

The TokenTypes type should be token, or an Either<L, R>, where L is a token, and R is either a token or another Either<L, R> with the same bound.

Required Associated Types

type TokenTypes: TokenTypes

The token types that this type can represent. See the trait documentation for more details.

Provided Methods

fn peek(input: ParseStream<'_>) -> bool

Returns true if the next token in input is any of the types in Self::TokenTypes.

The default implementation should never be overriden.

fn lookahead(lookahead: &Lookahead<'_>) -> bool

Returns true if lookahead is pointing to any of the types in Self::TokenTypes.

The default implementation should never be overriden.
