Expand description

A strategy trait for access to matrix elements.

Required Methods§

source

fn access(&self, m: &M, i: usize, j: usize) -> Option<(usize, usize)>

Gives the location (if it exists) of the element in a matrix that should match the indexes (subscripts) provided according to the access strategy.

A return of None is interpereted an out of bound access.

source

fn nrows(&self, m: &M) -> usize

Gives the number of rows for the Access matrix defined by the AccessStrategy.

source

fn ncols(&self, m: &M) -> usize

Gives the number of columns for the Access matrix defined by the AccessStrategy.
