pub(in infer::region_constraints::leak_check) fn assign_placeholder_values(
    &mut self
) -> RelateResult<'tcx, ()>[src]

Compute what placeholders (if any) each SCC must be equal to. Also compute the minimum universe of all the regions in each SCC.

pub(in infer::region_constraints::leak_check) fn assign_scc_value(
    &mut self,
    scc: LeakCheckScc,
    placeholder: PlaceholderRegion
) -> RelateResult<'tcx, ()>[src]

pub(in infer::region_constraints::leak_check) fn propagate_scc_value(
    &mut self
) -> RelateResult<'tcx, ()>[src]

For each SCC S, iterate over each successor S1 where S: S1:

  • Compute Iterate over each SCC S and ensure that, for each S1 where S1: S, universe(S) <= universe(S1). This executes after assign_placeholder_values, so universe(S) is already the minimum universe of any of its direct constituents.
