Array dimension trait.

Required Associated Types

type Merge<D: Dim>: Dim

Merge dimensions, where constant size is preferred over dynamic.

type FromExpr<T, S: Shape>: FromExpression<T, S::Prepend<Self>>

The resulting type after conversion from an expression.

Required Associated Constants

const SIZE: Option<usize>

Dimension size if known statically, or None if dynamic.

Required Methods

fn from_size(size: usize) -> Self

Creates an array dimension with the given size.

Panics

Panics if the size is not matching a constant-sized dimension.

fn size(self) -> usize

Returns the number of elements in the dimension.

Object Safety

This trait is not object safe.
