The input range. 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.
static array from CT range
import std.range : iota; enum a = staticArray!(2.iota); static assert(is(typeof(a) == int[2])); assert(a == [0, 1]); enum b = staticArray!(long, 2.iota); static assert(is(typeof(b) == long[2])); assert(b == [0, 1]);
static array from range + size
import std.range : iota; auto input = 3.iota; auto a = input.staticArray!2; static assert(is(typeof(a) == int[2])); assert(a == [0, 1]); auto b = input.staticArray!(long[4]); static assert(is(typeof(b) == long[4])); assert(b == [0, 1, 2, 0]);
Constructs a static array from a range. When a.length is not known at compile time, the number of elements must be given as a 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 be given as a template argument to avoid having to specify the number of elements (e.g.: staticArray!(2.iota) or staticArray!(double, 2.iota)).
