Struct syn::Generics [−] [src]

pub struct Generics {
    pub lt_token: Option<Lt>,
    pub params: Punctuated<GenericParam, Comma>,
    pub gt_token: Option<Gt>,
    pub where_clause: Option<WhereClause>,
}

Lifetimes and type parameters attached to a declaration of a function, enum, trait, etc.

Fields

lt_token: Option<Lt> params: Punctuated<GenericParam, Comma> gt_token: Option<Gt> where_clause: Option<WhereClause>

Methods

`impl Generics`
[src]

`pub fn split_for_impl( &self ) -> (ImplGenerics, TypeGenerics, Option<&WhereClause>)`
[src]

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 {
        // ...
    }
}
