Struct ParseMoreWrapper 

pub struct ParseMoreWrapper<T>(pub T);

This wrapper implements syn::parse::Parse when T implements ParseMore. It permits to use this wrapper and a type implementing ParseMore in a parsing function from syn.

You should probably use parse_more(), parse_more_macro_input, or any other function from this crate instead of using this type directly.

Example

use quote::quote;
use parse_more::ParseMoreWrapper;
use proc_macro::TokenStream;
use syn::{Ident, Token};

#[proc_macro]
pub fn flip_identifiers(input: TokenStream) -> TokenStream {
    let (ident_a, arrow, ident_b) = syn::parse::<ParseMoreWrapper<(Ident, Token![=>], Ident)>>(input).unwrap().0;
    quote! {
        #ident_b <= #ident_a
    }.into()
}
