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

Fields

Any lifetimes from a for binding

bounded_ty: Type

The type being bounded

colon_token: Colon

bounds: Punctuated<TypeParamBound, Plus>

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

Trait Implementations

impl Clone for PredicateType

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<PredicateType> for WherePredicate

fn from(e: PredicateType) -> WherePredicate

Converts to this type from the input type.

impl ToTokens for PredicateType

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStreamwhere Self: Sized,

Convert self directly into a TokenStream object.
