Struct ArrayView 

pub struct ArrayView<'a> { /* private fields */ }

Sources lent for one operation. The plan carries positions, never data or a materialization cache.

Implementations

impl<'a> ArrayView<'a>

pub fn new( layout: &'a Layout, sources: Vec<Binding<'a>>, plan: ReadPlan, ) -> Result<Self, Error>

pub fn compact(layout: &'a Layout, storage: View<'a>) -> Self

pub fn layout(&self) -> &'a Layout

pub fn dtype(&self) -> DType

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn read(&self) -> Read<'_>

pub fn plan(&self) -> &ReadPlan

pub fn sources(&self) -> &[Binding<'a>]

pub fn with_layout<'b>( &self, layout: &'b Layout, ) -> Result<ArrayView<'b>, Error>

where 'a: 'b,

Changes metadata, retaining the logical sequence.

pub fn remapped(&self, mapping: Mapping, items: usize) -> Self

Composes a call’s positional read. Missing positions read the prototype (Missing::prototype).

pub fn contiguous(&self) -> Option<View<'a>>

pub fn affine(&self) -> Option<(View<'a>, usize, Vec<isize>)>

pub fn cast(&self, dtype: DType) -> Result<Items<'a>, Error>

Borrows a contiguous read at its dtype, otherwise prepares exactly these logical items.

pub fn items<T: Element>(&self) -> Result<Cow<'a, [T]>, Error>

Trait Implementations

impl<'a> Clone for ArrayView<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
