Module rustc_infer::infer::opaque_types

source ·



  • Visitor that requires that (almost) all regions in the type visited outlive least_region. We cannot use push_outlives_components because regions in closure signatures are not included in their outlives components. We need to ensure all regions outlive the given bound so that we don’t end up with, say, ReVar appearing in a return type and causing ICEs when other functions end up with region constraints involving regions from other functions.
  • Information about the opaque types whose values we are inferring in this function (these are the impl Trait that appear in the return type).
