Struct IndexMatrix

Source 
pub struct IndexMatrix<'a, R, C: IndexedValue + 'a, S: BitSet, P: PointerFamily<'a>> { /* private fields */ }
Expand description

An unordered collections of pairs (R, C), implemented with a sparse bit-matrix.

“Sparse” means “hash map from rows to bit-sets of columns”. Subsequently, only column types C must be indexed, while row types R only need be hashable.
