this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Information about the formal type/lifetime parameters associated with an item or method. Analogous to hir::Generics.

Note that in the presence of a Self parameter, the ordering here is different from the ordering in a Substs. Substs are ordered as Self, *Regions, *Other Type Params, (...child generics) while this struct is ordered as regions = Regions types = [Self, *Other Type Params]
