PureGCAllocator

D's built-in garbage-collected allocator purified.

TODO remove and place with GCAllocator when https://github.com/dlang/phobos/pull/6432 has been merged.

Members

Functions

allocate void[] allocate(size_t 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.
collect void collect(): Undocumented in source. Be warned that the author may not have intended to support it.
deallocate bool deallocate(void[] b)
expand bool expand(void[] b, size_t delta)
goodAllocSize size_t goodAllocSize(size_t n)
reallocate bool reallocate(void[] b, size_t newSize)
resolveInternalPointer Ternary resolveInternalPointer(void* p, void[] result): 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.

Static variables

instance PureGCAllocator instance;: Returns the global instance of this allocator type. The garbage collected allocator is thread-safe, therefore all of its methods and instance itself 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.
