span

A fixed-size array type for SNEX.
The span type is an iteratable compile-time array. The elements can be accessed using the []-operator or via a range-based for loop.
In order to prevent unsafe out-of-bounds memory access, the []-operator access can either take a literal integer index (that will be compiled-time checked against the boundaries), or a index subtype with a defined out-of-bounds behaviour (wrapping, clamping, etc).

Static functions

as

Type & as(T *ptr)

Morphs any pointer of the data type into this type.

Class methods

toSimd

span< span< float, 4 >, Size/4 > & toSimd()

Converts this float span into a SSE span with 4 float elements at once. This checks at compile time whether the span can be converted.

begin

T * begin() const

This method allows a lean range-based for loop syntax:

span data;

for(auto& s: data)
    s = 0.5f;

size

int size() const

Returns the number of elements in this span.
