Struct SliceLayout 

pub struct SliceLayout<C: Coordinates> { /* private fields */ }

A layout containing a sub-slice of the inner layout.

Implementations

impl<C: Coordinates> SliceLayout<C>

pub fn new(start: C, size: C, checked: bool) -> Self

Create a new slice layout. checked determines whether bounds should be checked, or simply treated as always in bounds.

pub fn __expand_new( scope: &mut Scope, start: <C as CubeType>::ExpandType, size: <C as CubeType>::ExpandType, checked: bool, ) -> <Self as CubeType>::ExpandType

Trait Implementations

impl<C: Coordinates> CubeType for SliceLayout<C>

type ExpandType = SliceLayoutExpand<C>

fn into_mut(scope: &mut Scope, expand: Self::ExpandType) -> Self::ExpandType

Wrapper around the init method, necessary to type inference.

impl<C: Coordinates> Layout for SliceLayout<C>

type Coordinates = C

The coordinate type used by the conceptual tensor represented by this layout, i.e. (u32, u32, u32) for a fixed-rank 3D tensor. This does not have to match the rank of the underlying storage (if applicable). It’s only how the tensor is interpreted (viewed) by the code.

type SourceCoordinates = C

The coordinate type used by the inner storage wrapped in this layout, i.e. u32 for Array, or (u32, u32) for a 2D view.

fn shape(&self) -> Self::Coordinates

The shape of the conceptual tensor represented by this layout. Not necessarily the extent of the underlying storage, but only this view of it.

fn to_source_pos(&self, pos: Self::Coordinates) -> Self::SourceCoordinates

Transform a set of n-dimensional coordinates to a source coordinate space. It is recommended to use absolute positions here, and handle the translation into lines at the lowest level (global memory layout).

fn is_in_bounds(&self, pos: Self::Coordinates) -> bool

fn to_source_pos_checked( &self, pos: Self::Coordinates, ) -> (Self::SourceCoordinates, bool)

Transform a set of n-dimensional coordinates to an offset into the underlying storage, and return whether the position is in bounds of this layout. See also Layout::to_source_pos

fn __expand_to_source_pos( scope: &mut Scope, this: <Self as CubeType>::ExpandType, pos: <Self::Coordinates as CubeType>::ExpandType, ) -> <Self::SourceCoordinates as CubeType>::ExpandType

fn __expand_to_source_pos_checked( scope: &mut Scope, this: <Self as CubeType>::ExpandType, pos: <Self::Coordinates as CubeType>::ExpandType, ) -> <(Self::SourceCoordinates, bool) as CubeType>::ExpandType

fn __expand_shape( scope: &mut Scope, this: <Self as CubeType>::ExpandType, ) -> <Self::Coordinates as CubeType>::ExpandType

fn __expand_is_in_bounds( scope: &mut Scope, this: <Self as CubeType>::ExpandType, pos: <Self::Coordinates as CubeType>::ExpandType, ) -> <bool as CubeType>::ExpandType
