Oneshot

wrpc_transport::frame

Struct Oneshot 

Source 
pub struct Oneshot<I, O>(/* private fields */);
Expand description

Invoke and Accept implementation in terms of a single stream pair.

Either Invoke::invoke or Accept::accept can only be called at most once on Oneshot, repeated calls with return an error
