[][src]Struct rustc_data_structures::indexed_set::IdxSet

pub struct IdxSet<T: Idx>(BitArray<T>);
🔬 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?

Represents a set 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.

The representation is dense, using one bit per possible element.
