Enum rustc_ast::ast::ClosureBinder

pub enum ClosureBinder {
    NotPresent,
    For {
        span: Span,
        generic_params: P<[GenericParam]>,
    },
}

Closure lifetime binder, for<'a, 'b> in for<'a, 'b> |_: &'a (), _: &'b ()|.

Variants

NotPresent

The binder is not present, all closure lifetimes are inferred.

For

Fields

span: Span

Span of the whole for<> clause

for<'a, 'b> |_: &'a (), _: &'b ()| { ... }
^^^^^^^^^^^ -- this

generic_params: P<[GenericParam]>

Lifetimes in the for<> closure

for<'a, 'b> |_: &'a (), _: &'b ()| { ... }
    ^^^^^^ -- this

The binder is present.

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.
