Trait for types that can be iterated as sparse vectors

Required Associated Types

type IterType

Required Methods

fn into_sparse_vec_iter(self) -> <Self as IntoSparseVecIter<'a, N>>::IterType

where <Self as IntoSparseVecIter<'a, N>>::IterType: Iterator<Item = (usize, &'a N)>,

Transform self into an iterator that yields (usize, &N) tuples where the usize is the index of the value in the sparse vector. The indices should be sorted.

fn dim(&self) -> usize

The dimension of the vector

Provided Methods

fn is_dense(&self) -> bool

Indicator to check whether the vector is actually dense

fn index(self, idx: usize) -> &'a N

where Self: Sized,

Random access to an element in the vector.

Panics

• if the vector is not dense
• if the index is out of bounds
