Struct StackShape 

pub struct StackShape<const N: usize> {
    pub dims: [usize; N],
    pub ndim: usize,
}

Small shape stored on stack for zero-allocation operations

Fields

dims: [usize; N]

Dimensions stored on stack

ndim: usize

Actual number of used dimensions (may be less than N)

Implementations

impl<const N: usize> StackShape<N>

pub const fn new(dims: [usize; N]) -> Self

Create a new stack shape

pub fn from_slice(dims: &[usize]) -> Option<Self>

Create from slice with runtime length check

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

Get active dimensions as slice

pub const fn numel(&self) -> usize

Calculate total number of elements (no allocation)

pub fn to_shape(&self) -> Shape

Convert to heap-allocated Shape

pub fn broadcast_compatible<const M: usize>( &self, other: &StackShape<M>, ) -> bool

Broadcast compatibility check (no allocation)

Trait Implementations

impl<const N: usize> Clone for StackShape<N>

fn clone(&self) -> StackShape<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const N: usize> Debug for StackShape<N>

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

Formats the value using the given formatter.

impl<const N: usize> PartialEq for StackShape<N>

fn eq(&self, other: &StackShape<N>) -> 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.
