Required Methods

fn alloc(&self, ty: &Type) -> GcPtr

Allocates an object of the given type returning a GcPtr

fn alloc_array(&self, ty: &Type, n: usize) -> Self::Array

Allocates an array of the given type. ty must be an array type.

fn ptr_type(&self, obj: GcPtr) -> Type

Returns the type of the specified obj.

fn array(&self, handle: GcPtr) -> Option<Self::Array>

Returns array information of the specified handle

fn root(&self, obj: GcPtr)

Roots the specified obj, which keeps it and objects it references alive. Objects marked as root, must call unroot before they can be collected. An object can be rooted multiple times, but you must make sure to call unroot an equal number of times before the object can be collected.

fn unroot(&self, obj: GcPtr)

Unroots the specified obj, potentially allowing it and objects it references to be collected. An object can be rooted multiple times, so you must make sure to call unroot the same number of times as root was called before the object can be collected.

fn stats(&self) -> Stats

Returns stats about the current state of the runtime.
