Struct PredicateType

pub struct PredicateType {
    pub lifetimes: Option<BoundLifetimes>,
    pub bounded_ty: Type,
    pub colon_token: Colon,
    pub bounds: Punctuated<TypeParamBound, Plus>,
}

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

This is a custom variant of syn::PredicateType which supports trait as a parameter bound.

Fields

lifetimes: Option<BoundLifetimes>

Any lifetimes from a for binding

bounded_ty: Type

The type being bounded

colon_token: Colon

: before bounds

bounds: Punctuated<TypeParamBound, Plus>

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