HmodBlockAllocator

A somewhat incomplete (no dealloc) std.allocator implementation - passed to libdparse.

All data is deallocated in destructor.

Allocates memory in fixed-size blocks and tries to place allocations into those blocks. Allocations larger than a block fail.

Based on BlockAllocator from Brian Schott's containers library

struct HmodBlockAllocator (

size_t blockSize

) {

union __anonymous;

alias bytesHighTide = bytesAllocated;

union __anonymous;

union __anonymous;

union __anonymous;

union __anonymous;

void[] allocate(size_t bytes);

bool deallocate(void[] b);

Ternary owns(void[] b);

enum maxAllocationSize;

enum alignment;

void writeStats();

}

Destructor

~this ~this(): Frees all memory allocated by this allocator

Postblit

this(this) this(this): Copy construction disabled because this struct clears its memory with a destructor.

Members

Aliases

bytesHighTide alias bytesHighTide = bytesAllocated: The highest number of bytes allocated at any given moment.

Functions

allocate void[] allocate(size_t bytes): Standard allocator operation.
deallocate bool deallocate(void[] b): Dummy deallocation function, to keep track of how much the user tried to deallocate.
owns Ternary owns(void[] b): Was the given buffer allocated with this allocator?
writeStats void writeStats(): Write allocation statistics to standard output.

Manifest constants

alignment enum alignment;: Allocator's memory alignment
maxAllocationSize enum maxAllocationSize;: The maximum number of bytes that can be allocated at a time with this allocator. This is smaller than blockSize because of some internal bookkeeping information.
