core.gc.registry

alias GCFactory = GC function();

A factory function that instantiates an implementation of the GC interface. In case the instance was allocated on the C heap, it is supposed to free itself upon calling it's destructor.

The factory should print an error and abort the program if it cannot successfully initialize the GC instance.

nothrow @nogc void registerGCFactory(string name, GCFactory factory);

Register a GC factory under the given name. This function must be called from a C constructor before druntime is initialized.

To use the registered GC, it's name must be specified gcopt runtime option, e.g. by passing , --DRT-gcopt=gc:my_gc_name as application argument.

Parameters:

string name	name of the GC implementation; should be unique
GCFactory factory	function to instantiate the implementation

Note The registry does not perform synchronization, as registration is assumed to be executed serially, as is the case for C constructors.
