Module rustc_mir::dataflow[−][src]

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

at_location	[ Experimental ] A nice wrapper to consume dataflow results at several CFG locations.
drop_flag_effects	[ Experimental ]
graphviz	[ Experimental ] Hook into libgraphviz for rendering dataflow graphs for MIR.
impls	[ Experimental ] Dataflow analyses are built upon some interpretation of the bitvectors attached to each basic block, represented via a zero-sized structure.
move_paths	[ Experimental ]

AllSets	[ Experimental ]
Bits	[ Experimental ] Maps each block to a set of bits
BlockSets	[ Experimental ] Triple of sets associated with a given block.
DataflowAnalysis	[ Experimental ]
DataflowBuilder	[ Experimental ]
DataflowResults	[ Experimental ]
DataflowState	[ Experimental ] State of a dataflow analysis; couples a collection of bit sets with operator used to initialize and merge bits during analysis.
DebugFormatted	[ Experimental ] `DebugFormatted` encapsulates the "{:?}" rendering of some arbitrary value. This way: you pay cost of allocating an extra string (as well as that of rendering up-front); in exchange, you don't have to hand over ownership of your value or deal with borrowing it.
MoveDataParamEnv	[ Experimental ]
PropagationContext	[ Experimental ]

BitDenotation	[ Experimental ]
Dataflow	[ Experimental ]
DataflowResultsConsumer	[ Experimental ] DataflowResultsConsumer abstracts over walking the MIR with some already constructed dataflow results.
InitialFlow	[ Experimental ] Parameterization for the precise form of data flow that is used. `InitialFlow` handles initializing the bitvectors before any code is inspected by the analysis. Analyses that need more nuanced initialization (e.g. they need to consult the results of some other dataflow analysis to set up the initial bitvectors) should not implement this.
