[−][src]Struct mongodb::options::CountOptions
Specifies the options to a
Collection::count_documents
operation.
Fields
hint: Option<Hint>
The index to use for the operation.
limit: Option<i64>
The maximum number of documents to count.
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.
skip: Option<i64>
The number of documents to skip before counting.
collation: Option<Collation>
The collation to use for the operation.
See the documentation for more information on how to use this option.
Methods
impl CountOptions
[src]
pub fn builder() -> TypedBuilder_BuilderFor_CountOptions<(), (), (), (), ()>
[src]
Create a builder for building CountOptions
.
On the builder, call .hint(...)
(optional), .limit(...)
(optional), .max_time(...)
(optional), .skip(...)
(optional), .collation(...)
(optional) to set the values of the fields(they accept Into
values).
Finally, call .build()
to create the instance of CountOptions
.
