Struct rustc_index::bit_set::SparseBitSet

pub struct SparseBitSet<T> {
    domain_size: usize,
    elems: ArrayVec<[T; 8]>,
}

A fixed-size bitset type with a sparse representation and a maximum of SPARSE_MAX elements. The elements are stored as a sorted ArrayVec with no duplicates.

This type is used by HybridBitSet; do not use directly.

Fields

domain_size: usize

elems: ArrayVec<[T; 8]>
