Expand description

A type predicate in a where clause: for<'c> Foo<'c>: Trait<'c>.

This type is available only if Syn is built with the "derive" or "full" feature.

Fields

lifetimes: Option<BoundLifetimes>

Any lifetimes from a for binding

bounded_ty: Type

The type being bounded

colon_token: Colonbounds: Punctuated<TypeParamBound, Add>

Trait and lifetime bounds (Clone+Send+'static)
