}

Trait for simpler service implementation with run loops which may fail with TryService::ErrorType errors; otherwise they should never return

Associated Types

type ErrorType: Error

Type of the error which is produced in case of service failure and is returned from the internal [try_run_loop()] procedure

Required methods

#[must_use]pub fn try_run_loop<'async_trait>(
    self
) -> Pin<Box<dyn Future<Output = Result<(), Self::ErrorType>> + Send + 'async_trait>> where
    Self: 'async_trait, 

Main failable run loop implementation. Must produce an error of type TryService::ErrorType or never return.

Provided methods

#[must_use]pub fn run_or_panic<'life0, 'async_trait>(
    self,
    service_name: &'life0 str
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: Send + 'async_trait, 

NB: Do not reimplement this one: the function keeps in check that if the failure happens during run loop, the program will panic reporting the failure. To implement the actual run loop please provide implementation for [try_run_loop()]
