Struct CallOptions 

pub struct CallOptions {
    pub metadata: Metadata,
    pub timeout: Option<Duration>,
    pub max_message_bytes: Option<usize>,
}

Per-call options.

Fields

metadata: Metadata

timeout: Option<Duration>

Deadline for the call.

Sent as grpc-timeout and enforced locally, because the header alone guarantees nothing: it is a request to the far end, and a peer that ignores it leaves the caller waiting forever. The header still goes out so anything that does enforce it — a server, a proxy, an upstream — can.

On a stream this covers the whole call, not just its opening: one timer spans the request and every message read after it. Bounding only the open would miss the case the deadline exists for, a peer that answers promptly and then stalls.

max_message_bytes: Option<usize>

Reject an inbound message larger than this (RESOURCE_EXHAUSTED).
