pub trait FromSession {
    // Required methods

Expand description

Trait implemented by datatypes that are built from session data. This is used when subscribing to specific parsed application-layer data.

Required Methods§

Source

fn stream_protocols() -> Vec<&'static str>

The stream protocols (lower-case) required for this datatype. See IMPLEMENTED_PROTOCOLS in retina_core for list of supported protocols.

Source

fn from_session(session: &Session) -> Option<&Self>

Build Self from a parsed session, or return None if impossible. Invoked when the session is fully matched, parsed, and ready to be delivered to a callback.

Source

fn from_sessionlist(sessionlist: &SessionList) -> Option<&Self>

Build Self from a list of sessions, or return None if impossible. Invoked when the connection has terminated and a FromSession datatype must be delivered to a callback.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
