Struct SetupContext

Source 
pub struct SetupContext<S> { /* private fields */ }
Expand description

A SetupContext is made available to an operator’s setup method, and allows the operators to register deadlines for events along with their corresponding handlers. The generic type S is the State registered with the operator.
