Trait sprs::indexing::SpIndex

pub trait SpIndex: Debug + PrimInt + AddAssign<Self> + Default {
    fn index(self) -> usize;
    fn from_usize(ind: usize) -> Self;
}

A sparse matrix index

This is a convenience trait to enable using various integer sizes for sparse matrix indices.

Required methods

fn index(self) -> usize

Convert to usize

Panics

If the integer cannot be represented as an usize, eg negative numbers. The panic happens in debug builds only.

fn from_usize(ind: usize) -> Self

Convert from usize

Panics

If the input overflows the index type. The panic happens in debug builds only.
