emplace

Given a raw memory area chunk, constructs an object of non-class type T at that address. The constructor is passed the arguments args, if any. Preconditions: chunk must be at least as large as T needs and should have an alignment multiple of T's alignment. Note: This function can be @trusted if the corresponding constructor of T is @safe.

T* emplace(T* chunk)
T* emplace(T* chunk, Args args)
T emplace(T chunk, Args args)
T emplace(void[] chunk, Args args)
T* emplace(void[] chunk, Args args)
T*

(

)
(
void[] chunk
,
auto ref Args args
)
if (
!is(T == class)
)

Return Value

Type: T*

A pointer to the newly constructed object.

Examples

struct S
{
    int a, b;
}
void[S.sizeof] buf = void;
S s;
s.a = 42;
s.b = 43;
auto s1 = emplace!S(buf, s);
assert(s1.a == 42 && s1.b == 43);
