Expand description
Specifies the options to a
Collection::estimated_document_count
operation.
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.max_time: Option<Duration>
The maximum amount of time to allow the query to run.
This options maps to the maxTimeMS
MongoDB query option, so the duration will be sent
across the wire as an integer number of milliseconds.
selection_criteria: Option<SelectionCriteria>
The criteria used to select a server for this operation.
If none specified, the default set on the collection will be used.
read_concern: Option<ReadConcern>
The level of the read concern.
comment: Option<Bson>
Tags the query with an arbitrary BSON object to help trace the operation through the database profiler, currentOp and logs.
This option is only available on server versions 4.4+.
