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?

Represents a set (or packed family of sets), of some element type E, where each E is identified by some unique index type T.

In other words, T is the type used to index into the bitvector this type uses to represent the set of object it holds.
