emplace

core lifetime

Given a pointer chunk to uninitialized memory (but already typed as T), constructs an object of non-class type T at that address. If T is a class, initializes the class reference to null.

  1. T* emplace(T* chunk)
    @safe pure nothrow
    T*
    emplace
    (
    T
    )
    (
    T* chunk
    )
  2. T* emplace(T* chunk, Args args)
  3. T emplace(T chunk, Args args)
  4. T emplace(void[] chunk, Args args)
  5. T* emplace(void[] chunk, Args args)

Return Value

Type: T*

A pointer to the newly constructed object (which is the same as chunk).

Examples

static struct S
{
    int i = 42;
}
S[2] s2 = void;
emplace(&s2);
assert(s2[0].i == 42 && s2[1].i == 42);
interface I {}
class K : I {}

K k = void;
emplace(&k);
assert(k is null);

I i = void;
emplace(&i);
assert(i is null);
