Functions

alignedAllocate void[] alignedAllocate(size_t bytes, uint alignment): Allocates the size expressed in bytes aligned by alignment.
alignedReallocate bool alignedReallocate(void[] b, size_t newSize, uint alignment): Re-allocate memory to newsize bytes aligned by alignment.
allocate void[] allocate(size_t bytes): Allocates the size expressed in bytes.
deallocate bool deallocate(void[] b): Deallocate the specified memory block
expand bool expand(void[] b, size_t delta): Expands the array by increasing its length with the required delta.
goodAllocSize size_t goodAllocSize(size_t size): Return the memory size that will be allocated asking for the minimum required size.
owns Ternary owns(void[] b): Checks if the memory has been allocated by this allocator.
reallocate bool reallocate(void[] b, size_t newSize): Re-allocate memory to newsize bytes.
resolveInternalPointer Ternary resolveInternalPointer(void* p, void[] result): Resolves a pointer to get the full memory block.

Static variables

instance Mimallocator instance;: Returns the global instance of this allocator type. Mimallocator is thread-safe, all methods are shared.

Variables

alignment enum uint alignment;: The alignment is a static constant equal to platformAlignment, which ensures proper alignment for any D data type.
