Struct Delete

Source 
pub struct Delete<'a> { /* private fields */ }
Expand description

Deletes documents matching a query. Construct with Collection::delete_one or Collection::delete_many.

Implementations§

Source§

impl<'a> Delete<'a>

Source

pub fn session(self, value: impl Into<&'a mut ClientSession>) -> Self

Use the provided session when running the operation.

Source

pub fn with_options(self, value: impl Into<Option<DeleteOptions>>) -> Self

Set all options. Note that this will replace all previous values set.

Source

pub fn collation(self, value: Collation) -> Self

The collation to use for the operation.

See the documentation for more information on how to use this option.

Source

pub fn write_concern(self, value: WriteConcern) -> Self

The write concern for the operation.

Source

pub fn hint(self, value: Hint) -> Self

The index to use for the operation. Only available in MongoDB 4.4+.

Source

pub fn let_vars(self, value: Document) -> Self

Map of parameter names and values. Values must be constant or closed expressions that do not reference document fields. Parameters can then be accessed as variables in an aggregate expression context (e.g. “$$var”).

Only available in MongoDB 5.0+.

Source

pub fn comment(self, value: impl Into<Bson>) -> Self

Tags the query with an arbitrary Bson value to help trace the operation through the database profiler, currentOp and logs.

This option is only available on server versions 4.4+.

Source§

impl<'a> Delete<'a>

Source

pub fn run(self) -> Result<DeleteResult>

Available on crate feature sync only.

Synchronously execute this action.
