Struct mongodb::options::EstimatedDocumentCountOptions [−][src]
Specifies the options to a
Collection::estimated_document_count
operation.
Fields (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.
Implementations
impl EstimatedDocumentCountOptions
[src]
pub fn builder() -> EstimatedDocumentCountOptionsBuilder<((), (), ())>
[src]
Create a builder for building EstimatedDocumentCountOptions
.
On the builder, call .max_time(...)
(optional), .selection_criteria(...)
(optional), .read_concern(...)
(optional) to set the values of the fields (they accept Into
values).
Finally, call .build()
to create the instance of EstimatedDocumentCountOptions
.
