Struct IxDyn 

pub struct IxDyn { /* private fields */ }

A dynamic-rank dimension whose number of axes is determined at runtime.

Implementations

impl IxDyn

pub fn new(shape: &[usize]) -> Self

Create a new dynamic dimension from a slice.

Trait Implementations

impl Clone for IxDyn

fn clone(&self) -> IxDyn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IxDyn

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

Formats the value using the given formatter.

impl Dimension for IxDyn

const NDIM: Option<usize> = None

The number of axes, or None for dynamic-rank arrays.

type Smaller = IxDyn

Dimension type produced by removing one axis (#349). Mirrors ndarray’s RemoveAxis::Smaller. Used to express the rank of index_axis and remove_axis results at the type level so Array<T, Ix2>::index_axis(...) returns ArrayView<T, Ix1> instead of ArrayView<T, IxDyn>.

type Larger = IxDyn

Dimension type produced by inserting one axis (#349). Mirrors ndarray’s Larger. Used by insert_axis to preserve compile- time rank.

fn as_slice(&self) -> &[usize]

Return the shape as a slice.

fn as_slice_mut(&mut self) -> &mut [usize]

Return the shape as a mutable slice.

fn from_dim_slice(shape: &[usize]) -> Option<Self>

Construct a dimension from a slice of axis lengths.

fn ndim(&self) -> usize

Number of dimensions.

fn size(&self) -> usize

Total number of elements (product of all dimension sizes).

impl From<&[usize]> for IxDyn

fn from(shape: &[usize]) -> Self

Converts to this type from the input type.

impl From<Vec<usize>> for IxDyn

fn from(shape: Vec<usize>) -> Self

Converts to this type from the input type.

impl Hash for IxDyn

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for IxDyn

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