Trait Dispatch 

Source 
pub trait Dispatch: Send + Sync {
    // Required methods
    fn authenticate<'a>(
        &'a self,
        peer: &'a PeerInfo,
        first: Option<&'a [u8]>,
    ) -> BoxFut<'a, Result<SessionCtx, AuthError>>;
    fn open(&self, ctx: &SessionCtx) -> Box<dyn Session>;
}
Expand description

The shared application dispatch: authenticate a connection, then open a per-connection Session. One Arc<dyn Dispatch> is shared across every accepted connection, so it stays Send + Sync and behind &self.

Required Methods§

Source

fn authenticate<'a>( &'a self, peer: &'a PeerInfo, first: Option<&'a [u8]>, ) -> BoxFut<'a, Result<SessionCtx, AuthError>>

Resolve a SessionCtx from peer metadata and/or the first frame (a pre-resolved identity in PeerInfo, or an in-band Hello in first).

Source

fn open(&self, ctx: &SessionCtx) -> Box<dyn Session>

Open the per-connection Session once, after authenticate. It owns the connection’s mutable dispatch state that the shared Arc<Self> cannot hold behind &self; the engine threads &mut into it.

Dyn Compatibility§

This trait is dyn compatible.

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