FallbackTcpManager

ts_runtime::fallback_tcp

Struct FallbackTcpManager 

Source 
pub struct FallbackTcpManager { /* private fields */ }
Expand description

Manages the fallback-TCP handler registry and the lifecycle of the raw-SYN observer.

Built once from the application netstack channel and held by the runtime. Registering the first handler starts the observer; dropping the last FallbackTcpHandle stops it.

Implementations§

Source§

impl FallbackTcpManager

Source

pub fn new(channel: Channel) -> Self

Build a manager bound to the application netstack channel. The observer is not started until the first handler is registered.

Source

pub fn register( &self, cb: Arc<dyn Fn(SocketAddr, SocketAddr) -> FallbackDecision + Send + Sync>, ) -> FallbackTcpHandle

Register a fallback callback, returning a RAII handle that deregisters it on drop.

The first registration starts the raw-SYN observer; the last deregistration stops it.

where T: Any,

Source§

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.
