pub enum CasExpectation {
    Exact(Vec<u8>),
    Present,
}

Expected value shape for single-key compare-and-set operations.

Match one exact current value.

Present

Match any live value, but fail when the key is absent/tombstoned.

Trait Implementations

impl Clone for CasExpectation

fn clone(&self) -> CasExpectation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CasExpectation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CasExpectation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CasExpectation

impl PartialEq for CasExpectation

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
