Function chumsky::text::semantic_indentation

pub fn semantic_indentation<'a, C, Tok, T, F, E: Error<C> + 'a>(
    token: T,
    make_group: F
) -> impl Parser<C, Vec<Tok>, Error = E> + Clone + 'awhere
    C: Character + 'a,
    Tok: 'a,
    T: Parser<C, Tok, Error = E> + Clone + 'a,
    F: Fn(Vec<Tok>, E::Span) -> Tok + Clone + 'a,

A parser that consumes text and generates tokens using semantic whitespace rules and the given token parser.

Also required is a function that collects a Vec of tokens into a whitespace-indicated token tree.
