Function macro_tools::orphan::generic_params::names

source · 
pub fn names<'a>(
    generics: &'a Generics,
) -> impl IterTrait<'a, &'a Ident> + Clone
Expand description

Extracts the names of type parameters, lifetimes, and const parameters from the given Generics.

This function returns an iterator over the names of the parameters in the Generics, which can be useful for generating code that requires just the names of the parameters without their associated bounds or default values.

§Arguments

  • generics - The Generics instance from which to extract parameter names.

§Returns

Returns an iterator over the names of the parameters.

§Examples


let generics : syn::Generics = parse_quote!
{
  < T : Clone + Default, U, 'a, const N : usize >
};
let names : Vec< _ > = macro_tools::generic_params::names( &generics ).collect();

assert_eq!( names, vec!
[
  &syn::Ident::new( "T", proc_macro2::Span::call_site() ),
  &syn::Ident::new( "U", proc_macro2::Span::call_site() ),
  &syn::Ident::new( "a", proc_macro2::Span::call_site() ),
  &syn::Ident::new( "N", proc_macro2::Span::call_site() )
]);
