Struct rustc_index::bit_set::SparseBitSet

source ·
pub struct SparseBitSet<T> {
    domain_size: usize,
    elems: ArrayVec<T, SPARSE_MAX>,
}
Expand description

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.

Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
