Expand description

Factory for a family of transport schemes.

One implementation per transport backend. The implementation advertises which URL schemes it owns and constructs connected Transport handles or Listeners for them.

Required Methods§

Source

fn schemes(&self) -> &'static [&'static str]

URL schemes this kind owns, e.g. ["inproc"] or ["tcp", "tcp+tls"]. Claimed schemes must be in crate::url::KNOWN_SCHEMES.

Source

fn connect(&self, url: &Url) -> Result<Box<dyn Transport>>

Open a connected transport to the peer identified by url.

Source

fn listen(&self, url: &Url) -> Result<Box<dyn Listener>>

Begin listening for inbound connections at the address in url. Transports that cannot listen (client-only) return crate::error::Error::Unsupported.
