It would be nice to have also a lasso integration. |

Tbf, to avaid humongous types, trait "aliases" should be used.
pub type TokenParserExtra<'a> = Full<Rich<'a, Token>, (), ()>;
pub trait TokenInput<'a>: ValueInput<'a, Token = Token, Span = SimpleSpan> {}
impl<'a, T> TokenInput<'a> for T where T: ValueInput<'a, Token = Token, Span = SimpleSpan> {}
pub trait TokenParser<'a, I: TokenInput<'a>, O>:
Parser<'a, I, O, TokenParserExtra<'a>> + Clone {
}
impl<'a, I: TokenInput<'a>, O, T> TokenParser<'a, I, O> for T where T: Parser<'a, I, O, TokenParserExtra<'a>> + Clone {}until real trait aliases are available
Would this not be equivalent to: ident().map_with_state(|i, _, rodeo: &Rodeo| rodeo.get_or_intern(i)) |
Yes, I will use trait extensions for that then. |
