staticArray

Constructs a static array from a. The type of elements can be specified implicitly so that [1, 2].staticArray results in int[2], or explicitly, e.g. [1, 2].staticArray!float returns float[2]. When a is a range whose length is not known at compile time, the number of elements must be given as template argument (e.g. myrange.staticArray!2). Size and type can be combined, if the source range elements are implicitly convertible to the requested element type (eg: 2.iota.staticArray!(long[2])). When the range a is known at compile time, it can also be specified as a template argument to avoid having to specify the number of elements (e.g.: staticArray!(2.iota) or staticArray!(double, 2.iota)).

Note: staticArray returns by value, so expressions involving large arrays may be inefficient.

Parameters

a T[n]: The input elements. If there are less elements than the specified length of the static array, the rest of it is default-initialized. If there are more than specified, the first elements up to the specified length are used.

Return Value

Type: T[n]

A static array constructed from a.

Examples

static array from array literal

auto a = [0, 1].staticArray;
static assert(is(typeof(a) == int[2]));
assert(a == [0, 1]);
