) -> Self
pub fn new_gen_kill( tcx: TyCtxt<'tcx>, body: &'mir Body<'tcx>, analysis: A, ) -> Self
Creates a new Engine
to solve a gen-kill dataflow problem.

sourcepub fn new_generic(

body: &'mir Body<'tcx>,
analysis: A,
) -> Self
pub fn new_generic( tcx: TyCtxt<'tcx>, body: &'mir Body<'tcx>, analysis: A, ) -> Self
Creates a new Engine
to solve a dataflow problem with an arbitrary transfer
function.
Gen-kill problems should use new_gen_kill
, which will coalesce transfer functions for
better performance.
fn new( tcx: TyCtxt<'tcx>, body: &'mir Body<'tcx>, analysis: A, apply_statement_trans_for_block: Option<Box<dyn Fn(BasicBlock, &mut A::Domain)>>, ) -> Self
sourcepub fn pass_name(self, name: &'static str) -> Self
pub fn pass_name(self, name: &'static str) -> Self
Adds an identifier to the graphviz output for this particular run of a dataflow analysis.
Some analyses are run multiple times in the compilation pipeline. Give them a pass_name
to differentiate them. Otherwise, only the results for the latest run will be saved.
sourcepub fn iterate_to_fixpoint(self) -> Results<'tcx, A>where
A::Domain: DebugWithContext<A>,
pub fn iterate_to_fixpoint(self) -> Results<'tcx, A>where
A::Domain: DebugWithContext<A>,
Computes the fixpoint for this dataflow problem and returns it.

Layout§
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
