Module rustc_hir_analysis::coherence
source · Modules§
- builtin πCheck properties that are required by built-in traits and set up data structures required by type-checking/codegen.
- inherent_
impls πThe code in this module gathers up all of the inherent impls in the current crate and organizes them in a map. It winds up touching the whole crate and thus must be recomputed completely for any change, but it is very cheap to compute. In practice, most code in the compiler never directly requests this map. Instead, it requests the inherent impls specific to some type (viatcx.inherent_impls(def_id)
). That value, however, is computed by selecting an idea from this table. - orphan πOrphan checker: every impl either implements a trait defined in this crate or pertains to a type defined in this crate.
- unsafety πUnsafety checker: every impl either implements a trait defined in this crate or pertains to a type defined in this crate.
Functions§
- check_
impl π - check_
object_ πoverlap Checks whether an impl overlaps with the automaticimpl Trait for dyn Trait
. - coherent_
trait π - We allow impls of marker traits to overlap, so they canβt override impls as that could make it ambiguous which associated item to use.
- provide π
