Module buffer 

Compact buffers: owned items of one element type, borrowed views of them, and the DType that names each. Booleans take one byte each. Integers come in four widths, floats in three and complex numbers in two, named by the width of their parts. Source reads an item of one element type as another.

Structs

Fill

A fill that a call chooses: the item that a read gives at each position that reaches no item, as one native item, checked at the dtype that reads it. A read with no chosen fill gives its dtype’s Element::FILL. A frontend’s own storage, such as basedpl’s nested arrays, keeps its fills in the frontend.

Output

Scratch

Conversion buffers retained for one execution, by computing dtype and operand position.

Enums

Buffer

Items of one element type.

ComplexBuf

ComplexWidth

Complexes

DType

The element type of a compact buffer. Numbers widen from Boolean through the integer widths to the float widths to the complex widths.

FloatBuf

FloatWidth

Floats

IntBuf

Ints

Items

Compact items at one dtype, borrowed or prepared by gathering and conversion.

MapOutput

Where a map appends: an owned buffer or the next slots of a caller’s result.

View

A buffer’s items, borrowed in their element type.

Width

Traits

Cast

Convert stored items using the destination dtype’s checked conversion.

Element

An element type of compact buffers: bool, the integer widths u8, i16, i32 and i64, the float widths half::f16, f32 and f64, Complex32 and Complex64, and char.

OutputItem

Source

An item that reads as type A: a Boolean as a number, an integer as a wider integer, a float or a complex number, a float as a float of another width or a complex number, and a complex number as one of the other width.

Functions

read_all

Every item of items, read as type A, through the same scheduler as native elementwise calls.
