Struct GCType

Source 
#[repr(C)]
pub struct GCType(/* private fields */);
Expand description

Applications can register callback functions which will be called before and after certain garbage collection operations. Allocations are not allowed in the callback functions, you therefore cannot manipulate objects (set or delete properties for example) since it is possible such operations will result in the allocation of objects.
