🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

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