The set of possible update operators.

Fields

set: Document

Replaces the value of given fields with the specified values.

unset: BTreeSet<Cow<'static, str>>

Removes the specified fiels from documents. In arrays, only sets the element to null but does not remove it.

set_current_date: BTreeMap<Cow<'static, str>, DateTimeType>

Sets the value of the given fiels to the current date.

rename: BTreeMap<Cow<'static, str>, Cow<'static, str>>

Renames the given fields using the new name specified as the value.

inc: Document

Increments the specified fields by the given amount, which may be negative.

mul: Document

Multiplies the specified fields by the given factor.

min: Document

Sets the value of each field only if the specified value is less than the already-existing value of the respective field.

max: Document

Sets the value of each field only if the specified value is greater than the already-existing value of the respective field.

add_to_set: Document

Adds the values to the specified array-valued fields if they do not yet contain them.

Trait Implementations

impl Default for Modification

fn default() -> Modification

Returns the "default value" for a type.

impl PartialEq<Modification> for Modification

fn eq(&self, other: &Modification) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Modification) -> bool

This method tests for !=.

impl From<Modification> for UpdateSpec

fn from(modification: Modification) -> Self

Performs the conversion.

impl Clone for Modification

fn clone(&self) -> Modification

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Modification

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Modification

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where     __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Modification

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where     __S: Serializer,

Serialize this value into the given Serde serializer.
