Struct Stream 

pub struct Stream { /* private fields */ }

Implementations§

§

impl Stream

pub fn ignore_for_keep_alive(&mut self)

Ignore this stream in the Swarm’s connection-keep-alive algorithm.

By default, any active stream keeps a connection alive. For most protocols, this is a good default as it ensures that the protocol is completed before a connection is shut down. Some protocols like libp2p’s ping for example never complete and are of an auxiliary nature. These protocols should opt-out of the keep alive algorithm using this method.
