[][src]Enum syn::WherePredicate

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>.
