Enum syn::WherePredicate [−][src]
pub enum WherePredicate { Type(PredicateType), Lifetime(PredicateLifetime), Eq(PredicateEq), }
A single predicate in a where
clause: T: Deserialize<'de>
.
This type is available if Syn is built with the "derive"
or "full"
feature.
Syntax tree enum
This type is a syntax tree enum.
Variants
Type(PredicateType)
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.
Lifetime(PredicateLifetime)
A lifetime predicate in a where
clause: 'a: 'b + 'c
.
This type is available if Syn is built with the "derive"
or
"full"
feature.
Eq(PredicateEq)
An equality predicate in a where
clause (unsupported).
This type is available if Syn is built with the "derive"
or
"full"
feature.
