Struct Selector 

pub struct Selector<A, B>(/* private fields */);

Select two upgrades into one. Supports all the protocols supported by either sub-upgrade.

The protocols supported by the first element have a higher priority.

Implementations

impl<A, B> Selector<A, B>

pub fn new(a: A, b: B) -> Self

Combines two upgraders into an Selector.

The protocols supported by the first element have a higher priority.

Trait Implementations

impl<A: Clone, B: Clone> Clone for Selector<A, B>

fn clone(&self) -> Selector<A, B>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<A: Debug, B: Debug> Debug for Selector<A, B>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<A, B> UpgradeInfo for Selector<A, B>

where A: UpgradeInfo, B: UpgradeInfo,

type Info = EitherName<<A as UpgradeInfo>::Info, <B as UpgradeInfo>::Info>

Opaque type representing a negotiable protocol.

fn protocol_info(&self) -> Vec<Self::Info>

Returns the list of protocols that are supported. Used during the negotiation process.

impl<A, B, C> Upgrader<C> for Selector<A, B>

where A: Upgrader<C> + Send, B: Upgrader<C> + Send, C: Send + 'static,

type Output = EitherOutput<<A as Upgrader<C>>::Output, <B as Upgrader<C>>::Output>

Output after the upgrade has been successfully negotiated and the handshake performed.

fn upgrade_inbound<'async_trait>( self, socket: C, info: <Self as UpgradeInfo>::Info, ) -> Pin<Box<dyn Future<Output = Result<EitherOutput<A::Output, B::Output>, TransportError>> + Send + 'async_trait>>

where Self: 'async_trait,

After we have determined that the remote supports one of the protocols we support, this method is called to start the handshake.

fn upgrade_outbound<'async_trait>( self, socket: C, info: <Self as UpgradeInfo>::Info, ) -> Pin<Box<dyn Future<Output = Result<EitherOutput<A::Output, B::Output>, TransportError>> + Send + 'async_trait>>

where Self: 'async_trait,

After we have determined that the remote supports one of the protocols we support, this method is called to start the handshake.
