//                         ^^^^^^^^^^

Variants§

§

BoundPredicate

A type is expected to comply with a set of bounds

Fields

§type_: Type

The type that’s being constrained.

fn f<T>(x: T) where for<'a> &'a T: Iterator {}
//                              ^
§bounds: Vec<GenericBound>

The set of bounds that constrain the type.

fn f<T>(x: T) where for<'a> &'a T: Iterator {}
//                                 ^^^^^^^^
§generic_params: Vec<GenericParamDef>

Used for Higher-Rank Trait Bounds (HRTBs)

fn f<T>(x: T) where for<'a> &'a T: Iterator {}
//                  ^^^^^^^
§

LifetimePredicate

A lifetime is expected to outlive other lifetimes.

Fields

§lifetime: String

The name of the lifetime.

§outlives: Vec<String>

The lifetimes that must be encompassed by the lifetime.

§

EqPredicate

A type must exactly equal another type.

Fields

§lhs: Type

The left side of the equation.

§rhs: Term

The right side of the equation.
