Expand description

Specifies an interface class to be used as a tag for callback-based completion queues. This can be used directly, as the first element of a struct in C, or as a base class in C++. Its “run” value should be assigned to some non-member function, such as a static method.

Fields

functor_run: Option<unsafe extern "C" fn(arg1: *mut grpc_completion_queue_functor, arg2: c_int)>

The run member specifies a function that will be called when this tag is extracted from the completion queue. Its arguments will be a pointer to this functor and a boolean that indicates whether the operation succeeded (non-zero) or failed (zero)

inlineable: c_int

The inlineable member specifies whether this functor can be run inline. This should only be used for trivial internally-defined functors.

internal_success: c_int

The following fields are not API. They are meant for internal use.

internal_next: *mut grpc_completion_queue_functor
