impl<'a, 'b, 'tcx> LeakCheck<'a, 'b, 'tcx>
fn new( tcx: TyCtxt<'tcx>, outer_universe: UniverseIndex, max_universe: UniverseIndex, mini_graph: &'a MiniGraph<'tcx>, rcc: &'a mut RegionConstraintCollector<'b, 'tcx>, ) -> Self
sourcefn assign_placeholder_values(&mut self) -> RelateResult<'tcx, ()>
fn assign_placeholder_values(&mut self) -> RelateResult<'tcx, ()>
Compute what placeholders (if any) each SCC must be equal to. Also compute the minimum universe of all the regions in each SCC.
fn assign_scc_value( &mut self, scc: LeakCheckScc, placeholder: PlaceholderRegion, ) -> RelateResult<'tcx, ()>
sourcefn propagate_scc_value(&mut self) -> RelateResult<'tcx, ()>
fn propagate_scc_value(&mut self) -> RelateResult<'tcx, ()>
For each SCC S, iterate over each successor S1 where S: S1
:
- Compute
Iterate over each SCC
S
and ensure that, for eachS1
whereS1: S
,universe(S) <= universe(S1)
. This executes afterassign_placeholder_values
, souniverse(S)
is already the minimum universe of any of its direct constituents.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
