Trait libp2p_core::upgrade::UpgradeInfo

pub trait UpgradeInfo {
    type Info: ProtocolName + Clone;
    type InfoIter: IntoIterator<Item = Self::Info>;
    fn protocol_info(&self) -> Self::InfoIter;
}

Common trait for upgrades that can be applied on inbound substreams, outbound substreams, or both.

Associated Types

type Info: ProtocolName + Clone

Opaque type representing a negotiable protocol.

type InfoIter: IntoIterator<Item = Self::Info>

Iterator returned by protocol_info.

Required methods

fn protocol_info(&self) -> Self::InfoIter

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