Required Methods

fn apply_effects_in_range<'tcx, A>( analysis: &mut A, state: &mut A::Domain, block: BasicBlock, block_data: &BasicBlockData<'tcx>, effects: RangeInclusive<EffectIndex>, )

where A: Analysis<'tcx>,

Applies all effects between the given EffectIndexs.

effects.start() must precede or equal effects.end() in this direction.
