Modules

drop_flag_effects

elaborate_drops

errors 🔒

fmt

Custom formatting traits used when outputting Graphviz diagrams with the results of a dataflow analysis.

framework 🔒

A framework that can express both gen-kill and generic dataflow problems.

graphviz

A helpful diagram for debugging dataflow problems.

impls

Dataflow analyses are built upon some interpretation of the bitvectors attached to each basic block, represented via a zero-sized structure.

indexes 🔒

lattice

Traits used to represent lattices for use as the domain of a dataflow analysis.

move_paths

rustc_peek

storage

un_derefer

Structs

Backward

Dataflow that runs from the exit of a block (the terminator), to its entry (the first statement).

Engine

A solver for dataflow problems.

Forward

Dataflow that runs from the entry of a block (the first statement), to its exit (terminator).

MoveDataParamEnv

Results

A dataflow analysis that has converged to fixpoint.

ResultsCursor

Allows random access inspection of the results of a dataflow analysis.

Enums

CallReturnPlaces

List of places that are written to after a successful (non-unwind) return from a Call or InlineAsm.

Traits

Analysis

A dataflow problem with an arbitrarily complex transfer function.

AnalysisDomain

Defines the domain of a dataflow problem.

Direction

GenKill

The legal operations for a transfer function in a gen/kill problem.

GenKillAnalysis

A gen/kill dataflow problem.

JoinSemiLattice

A partially ordered set that has a least upper bound for any pair of elements in the set.

ResultsVisitable

Things that can be visited by a ResultsVisitor.

ResultsVisitor

SwitchIntEdgeEffects

A type that records the edge-specific effects for a SwitchInt terminator.

Functions

has_rustc_mir_with

visit_results

Calls the corresponding method in ResultsVisitor for every location in a mir::Body with the dataflow state at that location.

Type Definitions

ResultsRefCursor

A ResultsCursor that borrows the underlying Results.
