Struct InstantiatedClauses 

pub struct InstantiatedClauses<'tcx> {
    pub clauses: Vec<Unnormalized<'tcx, Clause<'tcx>>>,
    pub spans: Vec<Span>,
}

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 an InstantiatedClauses list from a GenericClauses by using the instantiate method. Note that this method reflects an important semantic invariant of InstantiatedClauses: while the GenericClauses are expressed in terms of the bound type parameters of the impl/trait/whatever, an InstantiatedClauses instance represented a set of bounds for some particular instantiation, meaning that the generic parameters have been instantiated with their values.

Example:

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

Here, the GenericClauses for Foo would contain a list of bounds like [[], [U:Bar<T>]]. Now if there were some particular reference like Foo<isize,usize>, then the InstantiatedClauses would be [[], [usize:Bar<isize>]].

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
