Methods

impl Generics

fn split_for_impl(&self) -> (ImplGenerics, TyGenerics, &WhereClause)

Split a type's generics into the pieces required for impl'ing a trait for that type.

let (impl_generics, ty_generics, where_clause) = generics.split_for_impl();
quote! {
    impl #impl_generics MyTrait for #name #ty_generics #where_clause {
        // ...
    }
}
