pub struct CommandStartedEvent {

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

command: Document

The command being run.

db: String

The name of the database the command is being run against.

command_name: String

The type of command being run, e.g. “find” or “hello”.

request_id: i32

The driver-generated identifier for the request. Applications can use this to identify the corresponding event triggered by the completion of this command (i.e. either CommandSucceededEvent or CommandFailedEvent).

connection: ConnectionInfo

Information about the connect the command will be run on.

service_id: Option<ObjectId>

If the client connection is to a load balancer, the id of the selected backend.
