Enum rustc_ast::ast::GenericArgs

pub enum GenericArgs {
    AngleBracketed(AngleBracketedArgs),
    Parenthesized(ParenthesizedArgs),
    ParenthesizedElided(Span),
}

The generic arguments and associated item constraints of a path segment.

E.g., <A, B> as in Foo<A, B> or (A, B) as in Foo(A, B).

Variants

AngleBracketed(AngleBracketedArgs)

The <'a, A, B, C> in foo::bar::baz::<'a, A, B, C>.

Parenthesized(ParenthesizedArgs)

The (A, B) and C in Foo(A, B) -> C.

ParenthesizedElided(Span)

(..) in return type notation.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
