pub enum SparseEntry<'a, T> {
    NonZero(&'a T),
    Zero,
}
Expand description

An entry in a sparse matrix.

Sparse matrices do not store all their entries explicitly. Therefore, entry (i, j) in the matrix can either be a reference to an explicitly stored element, or it is implicitly zero.

Variants

NonZero(&'a T)

The entry is a reference to an explicitly stored element.

Note that the naming here is a misnomer: The element can still be zero, even though it is explicitly stored (a so-called “explicit zero”).

Zero

The entry is implicitly zero, i.e. it is not explicitly stored.

Implementations

Returns the value represented by this entry.

Either clones the underlying reference or returns zero if the entry is not explicitly stored.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Checks if self is actually part of its subset T (and can be converted to it).
Use with care! Same as self.to_subset but without any property checks. Always succeeds.
