Modules

drop_flag_effects

elaborate_drops

errors 🔒

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

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

A helpful diagram for debugging dataflow problems.

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

indexes 🔒

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

This module provides a framework on top of the normal MIR dataflow framework to simplify the implementation of analyses that track information about the values stored in certain places. We are using the term “place” here to refer to a mir::Place (a place expression) instead of an interpret::Place (a memory location).

Structs

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

A solver for dataflow problems.

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

MoveDataParamEnv

A dataflow analysis that has converged to fixpoint.

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

A dataflow problem with an arbitrarily complex transfer function.

Defines the domain of a dataflow problem.

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.

SwitchIntEdgeEffects

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

Functions

has_rustc_mir_with

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.
