Trait Chain 

pub trait Chain:
    Send
    + Sync
    + 'static {
    // Required methods
    fn serve(
        &self,
        context: &mut Context<'_>,
    ) -> impl Future<Output = Outcome> + Send;
    fn is_empty(&self) -> bool;

    // Provided methods
    fn parallel_query(&self, _query: &Message<'_>) -> Option<Receiver<bool>> { ... }
    fn visit_enabled(&self, _visit: &mut dyn FnMut(&'static str)) { ... }
    fn metrics_enabled(&self) -> bool { ... }
    fn stacktrace(&self) -> bool { ... }
}

Statically dispatched Plugin Chain supplied by the Plugin registry.

Required Methods

fn serve( &self, context: &mut Context<'_>, ) -> impl Future<Output = Outcome> + Send

fn is_empty(&self) -> bool

Provided Methods

fn parallel_query(&self, _query: &Message<'_>) -> Option<Receiver<bool>>

fn visit_enabled(&self, _visit: &mut dyn FnMut(&'static str))

fn metrics_enabled(&self) -> bool

fn stacktrace(&self) -> bool

Whether contained Plugin panics should include a stacktrace.

Dyn Compatibility

This trait is not dyn compatible.

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