Struct rustc::middle::ty::GenericBoundsExperimental

pub struct GenericBounds<'tcx> {
    pub predicates: VecPerParamSpace<Predicate<'tcx>>,
}

Represents the bounds declared on a particular set of type parameters. Should eventually be generalized into a flag list of where clauses. You can obtain a GenericBounds list from a Generics by using the to_bounds method. Note that this method reflects an important semantic invariant of GenericBounds: while the bounds in a Generics are expressed in terms of the bound type parameters of the impl/trait/whatever, a GenericBounds instance represented a set of bounds for some particular instantiation, meaning that the generic parameters have been substituted with their values.

Example:

struct Foo<T,U:Bar<T>> { ... }

Here, the Generics for Foo would contain a list of bounds like [[], [U:Bar<T>]]. Now if there were some particular reference like Foo<int,uint>, then the GenericBounds would be [[], [uint:Bar<int>]].
