on-demand-ify custom_coerce_unsized_kind and inherent-impls by nikomatsakis · Pull Request #40683 · rust-lang/rust (original) (raw)

There are now 3 queries:

• inherent_impls(def-id): for a given type, get a Rc<Vec<DefId>> with all its inherent impls. This internally uses crate_inherent_impls, doing some hacks to keep the current deps (which, btw, are not clearly correct).
• crate_inherent_impls(crate): gathers up a map from types to Rc<Vec<DefId>>, touching the entire krate, possibly generating errors.
• crate_inherent_impls_overlap_check(crate): performs overlap checks between the inherent impls for a given type, generating errors.
