Array shape and index trait.

This trait defines a number of methods and operations that can be used on dimensions and indices.

Note: This trait can not be implemented outside the crate

Associated Types

SliceArg is the type which is used to specify slicing for this dimension.

For the fixed size dimensions it is a fixed size array of the correct size, which you pass by reference. For the dynamic dimension it is a slice.

  • For Ix1: [Si; 1]
  • For Ix2: [Si; 2]
  • and so on..
  • For IxDyn: [Si]

The easiest way to create a &SliceArg is using the macro s![].

Pattern matching friendly form of the dimension value.

  • For Ix1: usize,
  • For Ix2: (usize, usize)
  • and so on..
  • For IxDyn: IxDyn

Next smaller dimension (if applicable)

Required Methods

Convert the dimension into a pattern matching friendly value.

This trait is private to implement; this method exists to make it impossible to implement outside the crate.

Provided Methods

Compute the size of the dimension (number of elements)

Compute the size while checking for overflow.

Borrow as a read-only array view.

Borrow as a read-write array view.
