Implementations

impl MatrixLayout

pub fn size(&self) -> (i32, i32)

pub fn resized(&self, row: i32, col: i32) -> MatrixLayout

pub fn lda(&self) -> i32

pub fn len(&self) -> i32

pub fn is_empty(&self) -> bool

pub fn same_order(&self, other: &MatrixLayout) -> bool

pub fn toggle_order(&self) -> Self

pub fn t(&self) -> Self

Transpose without changing memory representation

C-contigious row=2, lda=3

[[1, 2, 3]
 [4, 5, 6]]

and F-contigious col=2, lda=3

[[1, 4]
 [2, 5]
 [3, 6]]

have same memory representation [1, 2, 3, 4, 5, 6], and this toggles them.

let layout = MatrixLayout::C { row: 2, lda: 3 };
assert_eq!(layout.t(), MatrixLayout::F { col: 2, lda: 3 });

Trait Implementations

impl Clone for MatrixLayout

fn clone(&self) -> MatrixLayout

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MatrixLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MatrixLayout

fn eq(&self, other: &MatrixLayout) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
