Struct syn::PredicateType
[−]
[src]
pub struct PredicateType { pub lifetimes: Option<BoundLifetimes>, pub bounded_ty: Type, pub colon_token: Colon, pub bounds: Punctuated<TypeParamBound, Add>, }
A type predicate in a where
clause: for<'c> Foo<'c>: Trait<'c>
.
This type is available 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: Colon
bounds: Punctuated<TypeParamBound, Add>
Trait and lifetime bounds (Clone+Send+'static
)
