Implementations

impl UpdateOp

pub fn set(field: impl Into<String>, value: impl Into<JsonValue>) -> Self

Create a $set operation.

pub fn unset(field: impl Into<String>) -> Self

Create an $unset operation.

pub fn inc(field: impl Into<String>, amount: f64) -> Self

Create an $inc operation.

pub fn to_bson(&self) -> Value

Convert to BSON document.

Trait Implementations

impl Clone for UpdateOp

fn clone(&self) -> UpdateOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UpdateOp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UpdateOp

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for UpdateOp

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for UpdateOp

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
