Struct OpportunitySet 

Source 
struct OpportunitySet<'a, 'tcx> {
    basic_blocks: &'a mut IndexVec<BasicBlock, BasicBlockData<'tcx>>,
    entry_states: IndexVec<BasicBlock, ConditionSet>,
    duplicates: FxHashMap<(BasicBlock, ConditionIndex), BasicBlock>,
}

Fields§

§basic_blocks: &'a mut IndexVec<BasicBlock, BasicBlockData<'tcx>>§entry_states: IndexVec<BasicBlock, ConditionSet>§duplicates: FxHashMap<(BasicBlock, ConditionIndex), BasicBlock>

Cache duplicated block. When cloning a basic block bb to fulfill a condition c, record the target of this bb with c edge.
