Struct rustc_trait_selection::traits::util::Elaborator

pub struct Elaborator<'tcx> {
    stack: Vec<Obligation<'tcx, Predicate<'tcx>>, Global>,
    visited: PredicateSet<'tcx>,
}

“Elaboration” is the process of identifying all the predicates that are implied by a source predicate. Currently, this basically means walking the “supertraits” and other similar assumptions. For example, if we know that T: Ord, the elaborator would deduce that T: PartialOrd holds as well. Similarly, if we have trait Foo: 'static, and we know that T: Foo, then we know that T: 'static.

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.
