Struct BlockLayout 

pub struct BlockLayout { /* private fields */ }

Which block each element of a tensor falls in, for a block scheme. A block is a rectangle, so its members are a run of the flat storage only when it spans the trailing dimension; anything walking values against block scales asks here rather than chunking.

Implementations

impl BlockLayout

pub fn new(shape: &Shape, block: &BlockSize) -> BlockLayout

How block tiles a tensor of shape.

pub fn num_blocks(&self) -> usize

How many blocks the tensor holds, which is how many block scales it has.

pub fn divides(&self) -> bool

Whether every dimension is a whole number of blocks.

pub fn block_of(&self, index: usize) -> usize

The row-major index of the block holding row-major element index.

Trait Implementations

impl Clone for BlockLayout

fn clone(&self) -> BlockLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockLayout

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