allocate
(bytes)
|
Standard allocator methods per the semantics defined above. The
deallocate and reallocate methods are @system because they
may move memory around, leaving dangling pointers in user code. Somewhat
paradoxically, malloc is @safe but that's only useful to safe
programs that can afford to leak memory allocated.

deallocate
(b)
|
Standard allocator methods per the semantics defined above. The
deallocate and reallocate methods are @system because they
may move memory around, leaving dangling pointers in user code. Somewhat
paradoxically, malloc is @safe but that's only useful to safe
programs that can afford to leak memory allocated.

reallocate
(b, s)
|
Standard allocator methods per the semantics defined above. The
deallocate and reallocate methods are @system because they
may move memory around, leaving dangling pointers in user code. Somewhat

Example
auto buffer = Mallocator .instance .allocate(1024 * 1024 * 4);
scope(exit) Mallocator .instance .deallocate(buffer);
