Trait ReserveBiStreams 

pub trait ReserveBiStreams: Connection {
    type Reservation: BiReservation<SendStream = Self::SendStream, RecvStream = Self::RecvStream>;

    // Required methods
    fn try_reserve_bi(
        &self,
    ) -> Result<Option<Self::Reservation>, ConnectionError>;
    fn subscribe_bi_stream_budget(&self, listener: Weak<dyn ChangeListener>);
}
Available on crate features http-backend and http and std only.
Expand description

Exact stream credit for a multiplexing connection pool, see SendRequest::connection_admission.

Required Associated Types§

type Reservation: BiReservation<SendStream = Self::SendStream, RecvStream = Self::RecvStream>

Required Methods§

fn try_reserve_bi(&self) -> Result<Option<Self::Reservation>, ConnectionError>

None before the handshake completes or while credit is exhausted.

fn subscribe_bi_stream_budget(&self, listener: Weak<dyn ChangeListener>)

Notify listener when locally initiated bidirectional stream credit becomes available, the handshake completes, or the connection closes, until the listener is dropped. Acquiring or consuming a reservation need not notify listeners. Subscribe before trying to reserve credit to avoid missing a notification.

Dyn Compatibility§

This trait is not dyn compatible.

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