Module rustc_data_structures::bit_set

Structs

BitIter
BitMatrix	A fixed-size 2D bit matrix type with a dense representation.
BitSet	A fixed-size bitset type with a dense representation. It does not support resizing after creation; use GrowableBitSet for that.
GrowableBitSet	A resizable bitset type with a dense representation.
SparseBitMatrix	A fixed-column-size, variable-row-size 2D bit matrix with a moderately sparse representation.
SparseBitSet	A fixed-size bitset type with a sparse representation and a maximum of SPARSE_MAX elements. The elements are stored as a sorted SmallVec with no duplicates; although SmallVec can spill its elements to the heap, that never happens within this type because of the SPARSE_MAX limit.

Enums

HybridBitSet	A fixed-size bitset type with a hybrid representation: sparse when there are up to a SPARSE_MAX elements in the set, but dense when there are more than SPARSE_MAX.

WORD_BITS
WORD_BYTES

Traits

SubtractFromBitSet	This is implemented by all the bitsets so that BitSet::subtract() can be passed any type of bitset.
UnionIntoBitSet	This is implemented by all the bitsets so that BitSet::union() can be passed any type of bitset.
