Enum TensorIterOrder

pub enum TensorIterOrder {
    C,
    F,
    A,
    K,
    G,
    B,
}

The policy of the tensor iterator.

Variants

C

Row-major order.

• absolute safe for array iteration

F

Column-major order.

• absolute safe for array iteration

A

Automatically choose row/col-major order.

• try c/f-contig first (also see TensorIterOrder::B),

• try c/f-prefer second (also see TensorIterOrder::C, TensorIterOrder::F),

• otherwise FlagOrder::default(), which is defined by crate feature f_prefer.

• safe for multi-array iteration like get_iter(a, b)

• not safe for cases like a.iter().zip(b.iter())

K

Greedy when possible (reorder layouts during iteration).

• safe for multi-array iteration like get_iter(a, b)
• not safe for cases like a.iter().zip(b.iter())
• if it is used to create a new array, the stride of new array will be in K order

G

Greedy when possible (reset dimension to 1 if axis is broadcasted).

• not safe for multi-array iteration like get_iter(a, b)
• this is useful for inplace-assign broadcasted array.

B

Sequential buffer.

• not safe for multi-array iteration like get_iter(a, b)
• this is useful for reshaping or all-contiguous cases.

Trait Implementations

impl ChangeableDefault for TensorIterOrder

unsafe fn change_default(val: TensorIterOrder)

Safety

fn get_default() -> TensorIterOrder

impl Clone for TensorIterOrder

fn clone(&self) -> TensorIterOrder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TensorIterOrder

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

Formats the value using the given formatter.

impl Default for TensorIterOrder

where TensorIterOrder: ChangeableDefault,

fn default() -> TensorIterOrder

Returns the “default value” for a type.

impl PartialEq for TensorIterOrder

fn eq(&self, other: &TensorIterOrder) -> 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.
