Trait Implementations

impl<T: Doc> Count<T> for Document

fn filter(&self) -> Document

Filter for this query. Defaults to an empty filter, yielding the number of all documents in the collection.

fn options() -> CountOptions

Options for this query.

impl<T: Doc> Query<T> for Document

type Output = T

The type of the results obtained by executing the query. Often it's just the document type, T. TODO(H2CO3): make it default to T (#29661).

fn filter(&self) -> Document

Filter for restricting returned values. Defaults to an empty filter, resulting in all documents of the collection being returned.

fn transform(raw: Document) -> Result<Bson>

Optional transform applied to each returned raw document. Can be used to adjust the structure of the loosely-typed data so that it fits what is expected by <Self::Output as Deserialize>::deserialize().

fn options() -> FindOptions

Options for this query.

impl<T: Doc> Delete<T> for Document

fn filter(&self) -> Document

Filter for restricting documents to delete.

fn options() -> WriteConcern

Writing options for this deletion operation.
