Struct SharedMessageCounter 

Source 
pub struct SharedMessageCounter(/* private fields */);
Expand description

Wrapper around a Weak OwnedMessageCounter that can be passed around to keep the container awake.

Each live SharedMessageCounter is responsible for a pending message while it in scope, and removes it from the counter when it goes out of scope. Processes that need to cooperate can pass a SharedMessageCounter to each other to ensure that once the work is done, the lock goes out of scope as well. This allows for precise accounting of remaining work, and should give us control over container suspension which is guarded by the compiler, not conventions.
