Module closure

Structs

CaptureInfo

Part of MinCaptureInformationMap; describes the capture kind (&, &mut, move) for a particular capture as well as identifying the part of the source code that triggered this capture to occur.

CapturedPlace

A composite describing a Place that is captured by a closure.

ClosureTypeInfo

UpvarId

Upvars do not get their own NodeId. Instead, we use the pair of the original var ID (that is, the root variable that is referenced by the upvar) and the ID of the closure expression.

UpvarPath

Enums

BorrowKind

UpvarCapture

Information describing the capture of an upvar. This is computed during typeck, specifically by regionck.

Constants

CAPTURE_STRUCT_LOCAL

Captures are represented using fields inside a structure. This represents accessing self in the closure structure

Functions

closure_typeinfo 🔒

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.

Type Aliases

MinCaptureInformationMap

Given the closure DefId this map provides a map of root variables to minimum set of CapturedPlaces that need to be tracked to support all captures of that closure.

MinCaptureList

Part of MinCaptureInformationMap; List of CapturePlaces.

RootVariableMinCaptureList

Part of MinCaptureInformationMap; Maps a root variable to the list of CapturedPlace. Used to track the minimum set of Places that need to be captured to support all Places captured by the closure starting at a given root variable.
