Trait ServiceBuilder 

pub trait ServiceBuilder<S, Srvc>
where
    S: Clone + Send + Sync + 'static,
    AppContext: FromRef<S>,
    Srvc: Service<S>,
{
    // Required methods
    fn name(&self) -> String;
    fn enabled(&self, state: &S) -> bool;
    fn build<'life0, 'async_trait>(
        self,
        state: &'life0 S,
    ) -> Pin<Box<dyn Future<Output = RoadsterResult<Srvc>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Trait used to build a Service. It’s not a requirement that services implement this trait; it is provided as a convenience. A builder can be provided to the ServiceRegistry instead of a Service, in which case the ServiceRegistry will only build and register the service if Service::enabled is true.

Required Methods

fn name(&self) -> String

fn enabled(&self, state: &S) -> bool

fn build<'life0, 'async_trait>( self, state: &'life0 S, ) -> Pin<Box<dyn Future<Output = RoadsterResult<Srvc>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
