Module as_place

See docs in build/expr/mod.rs

Structs

• PlaceBuilder 🔒
  PlaceBuilder is used to create places during MIR construction. It allows you to “build up” a place by pushing more and more projections onto the end, and then convert the final set into a place using the to_place method.

Enums

• PlaceBase 🔒
  The “outermost” place that holds this value.

Functions

• convert_to_hir_projections_and_truncate_for_capture 🔒
  Given a list of MIR projections, convert them to list of HIR ProjectionKind. The projections are truncated to represent a path that might be captured by a closure/coroutine. This implies the vector returned from this function doesn’t contain ProjectionElems Downcast, ConstantIndex, Index, or Subslice because those will never be part of a path that is captured by a closure. We stop applying projections once we see the first projection that isn’t captured by a closure.
• enable_precise_capture 🔒
  Precise capture is enabled if user is using Rust Edition 2021 or higher.
• find_capture_matching_projections 🔒
  Given a closure, returns the index of a capture within the desugared closure struct and the ty::CapturedPlace which is the ancestor of the Place represented using the var_hir_id and projection.
• is_ancestor_or_same_capture 🔒
  Return true if the proj_possible_ancestor represents an ancestor path to proj_capture or proj_possible_ancestor is same as proj_capture, assuming they both start off of the same root variable.
• strip_prefix 🔒
  Returns projections remaining after stripping an initial prefix of HIR projections.
• to_upvars_resolved_place_builder 🔒
  Takes an upvar place and tries to resolve it into a PlaceBuilder with PlaceBase::Local
