std.array.array - multiple declarations

Function array

Allocates an array and initializes it with copies of the elements of range r.

ForeachType!Range[] array(Range) (
  Range r
)
if (isIterable!Range && !isNarrowString!Range && !isInfinite!Range);

ForeachType!(PointerTarget!Range)[] array(Range) (
  Range r
)
if (isPointer!Range && isIterable!(PointerTarget!Range) && !isNarrowString!Range && !isInfinite!Range);

Narrow strings are handled as a special case in an overload.

Parameters

NameDescription
r range (or aggregate with opApply function) whose elements are copied into the allocated array

Returns

allocated and initialized array

Example

auto a = array([1, 2, 3, 4, 5][]);
writeln(a); // [1, 2, 3, 4, 5]

Function array

Convert a narrow string to an array type that fully supports random access. This is handled as a special case and always returns an array of dchar

CopyTypeQualifiers!(ElementType!String,dchar)[] array(String) (
  scope String str
)
if (isNarrowString!String);

Parameters

NameDescription
str isNarrowString to be converted to an array of dchar

Returns

a dchar[], const(dchar)[], or immutable(dchar)[] depending on the constness of the input.

Example

import std.range.primitives : isRandomAccessRange;

writeln("Hello D".array); // "Hello D"d

writeln("Hello D"w.array); // "Hello D"d
static assert(isRandomAccessRange!dstring == true);
