Enum AttributeAction 

pub enum AttributeAction {
    Put,
    Delete,
    Add,

Add

Add to a number or set attribute.

Implementations

impl AttributeAction

pub fn as_str(&self) -> &'static str

Returns the DynamoDB wire-format string representation.

Trait Implementations

impl Clone for AttributeAction

fn clone(&self) -> AttributeAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeAction

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

Formats the value using the given formatter.

impl Default for AttributeAction

fn default() -> AttributeAction

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AttributeAction

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AttributeAction

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

Formats the value using the given formatter.

impl Hash for AttributeAction

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AttributeAction

fn eq(&self, other: &AttributeAction) -> 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 AttributeAction

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
