Struct tarpc::context::Context [−][src]
#[non_exhaustive]pub struct Context {
pub deadline: SystemTime,
pub trace_context: Context,
}
Expand description
A request context that carries request-scoped information like deadlines and trace information. It is sent from client to server and is used by the server to enforce response deadlines.
The context should not be stored directly in a server implementation, because the context will be different for each request in scope.
Fields (Non-exhaustive)
This struct is marked as non-exhaustive
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.deadline: SystemTime
When the client expects the request to be complete by. The server should cancel the request if it is not complete by this time.
trace_context: Context
Uniquely identifies requests originating from the same source.
When a service handles a request by making requests itself, those requests should
include the same trace_id
as that included on the original request. This way,
users can trace related actions across a distributed system.
