allocator

Allocators are classes that define memory models to be used by some parts of the C++ Standard Library, and most specifically, by STL containers.

extern (C++)

struct allocator (

T

) {

this(allocator!U );

alias size_type = size_t;

alias difference_type = ptrdiff_t;

alias pointer = T*;

alias value_type = T;

enum propagate_on_container_move_assignment;

enum is_always_equal;

alias rebind(U) = allocator!U;

version(CppRuntime_Microsoft)

T* allocate(size_t count);

version(CppRuntime_Microsoft)

void deallocate(T* ptr, size_t count);

version(CppRuntime_Microsoft)

enum size_t max_size;

version(!CppRuntime_Microsoft)
version(CppRuntime_Gcc)

T* allocate(size_t count, const(void)* );

version(!CppRuntime_Microsoft)
version(CppRuntime_Gcc)

void deallocate(T* ptr, size_t count);

version(!CppRuntime_Microsoft && CppRuntime_Gcc)

enum size_t max_size;

version(!CppRuntime_Microsoft)

version(CppRuntime_Clang)

T* allocate(size_t count, const(void)* );
