Struct rustc_infer::infer::region_constraints::TaintDirections

pub struct TaintDirections {
    incoming: bool,
    outgoing: bool,
}

When working with placeholder regions, we often wish to find all of the regions that are either reachable from a placeholder region, or which can reach a placeholder region, or both. We call such regions tainted regions. This struct allows you to decide what set of tainted regions you want.
