Struct Layout 

pub struct Layout<T> { /* private fields */ }

A validated layout for Matrix or MatrixMut.

This type guarantees the following invariants:

• self.nrows() * self.ncols() does not exceed usize::MAX.
• self.nrows() * self.ncols() * std::mem::size_of::<T>() does not exceed isize::MAX.

Implementations

impl<T> Layout<T>

pub const fn new(nrows: usize, ncols: usize) -> Result<Self, LayoutError>

Construct a new Layout, validating the following:

• nrows * ncols does not exceed usize::MAX.
• nrows * ncols * std::mem::size_of::<T>() does not exceed isize::MAX (the maximum addressable byte span).

pub fn num_elements(&self) -> usize

Return the product self.nrows() * self.ncols().

pub fn nrows(&self) -> usize

Return the number of rows.

pub fn ncols(&self) -> usize

Return the number of columns.

pub fn rebind<U>(&self) -> Result<Layout<U>, LayoutError>

Rebind the element type to U.

Errors

Returns an error if the rebound layout’s byte size would exceed isize::MAX.

pub fn transpose(&self) -> Layout<T>

Swap the rows and columns.
