Struct SessionContext 

pub struct SessionContext {
    pub session_id: String,
    pub caller: CallerIdentity,
    pub created_at: u64,
    pub expires_at: Option<u64>,
    pub request_count: u64,
    pub bytes_read: u64,
    pub bytes_written: u64,
    pub delegation_depth: u32,
    pub metadata: Option<Value>,
}

Per-session context carried through the Chio HTTP pipeline. A session groups related requests from the same caller over a bounded time window.

Fields

session_id: String

Unique session identifier.

caller: CallerIdentity

The authenticated caller for this session.

created_at: u64

Unix timestamp (seconds) when the session was created.

expires_at: Option<u64>

Unix timestamp (seconds) when the session expires. Guards may deny requests after this time.

request_count: u64

Number of requests evaluated in this session so far.

bytes_read: u64

Cumulative bytes read by this session (for data-flow guards).

bytes_written: u64

Cumulative bytes written by this session (for data-flow guards).

delegation_depth: u32

Current delegation depth (0 = direct caller).

metadata: Option<Value>

Optional metadata for extensibility.

Implementations
