Enum Action 

pub enum Action {
    Set(Value),
    Increment(f64),
    Append(Vec<Value>),
    Prepend(Vec<Value>),
    Delete,
}

Enum specifying the variants of actions to be performed when updating the item. The type contains factory methods to facilitate the construction of variants. Check deta docs for more information.

Variants

Set(Value)

The attribute to be updated or created.

Increment(f64)

The attribute to be incremented. Increment value can be negative.

Append(Vec<Value>)

The attribute to append a values to.

Prepend(Vec<Value>)

The attribute to prepend a values to.

Delete

The attribute to be deleted.

Implementations

impl Action

Factory methods.

where T: Serialize,

pub fn append_many<T>(value: &[T]) -> Result<Self>

where T: Serialize,

pub fn prepend<T>(value: T) -> Result<Self>

where T: Serialize,

pub fn prepend_many<T>(value: &[T]) -> Result<Self>

pub fn delete() -> Self

Trait Implementations

impl Clone for Action

fn clone(&self) -> Action

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Action

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

Formats the value using the given formatter.

impl From<Action> for Result<Action>

Useful conversion to wrap an Action type value to serde_json::Result for standardization purposes inside the Updates type.

fn from(action: Action) -> Result<Action>

Converts to this type from the input type.
