Struct LogContext 

pub struct LogContext<'a> {
    pub session_id: Ulid,
    pub request_id: Option<Ulid>,
    pub cluster_id: Option<&'a str>,
    pub backend_id: Option<&'a str>,
}

Prefix block attached to every log line. Rendered as [<session_id> <request_id_or_-> <cluster_id_or_-> <backend_id_or_->] so operators can grep a full TCP/TLS session (session_id) or drill into one HTTP exchange (request_id).

• session_id is generated once per mio-accepted socket and survives protocol upgrades (expect-proxy, TLS handshake, H1↔H2 multiplexing).
• request_id is per-request: distinct for each H2 stream, and regenerated on each H1 keep-alive exchange.

Fields

session_id: Ulid

request_id: Option<Ulid>

cluster_id: Option<&'a str>

backend_id: Option<&'a str>
