Enum MissingKeyPolicy 

pub enum MissingKeyPolicy {
    Match,
    NoMatch,
}

Policy that controls how filters treat missing keys for negative predicates.

The policy only affects crate::Condition::NotEqual and crate::Condition::NotIn. Other predicates keep their existing semantics (equal requires presence, exists / not_exists check presence directly, etc.).

Variants

Match

Missing keys satisfy negative predicates (not_equal, not_in_values).

This is the historical behavior and therefore the default.

NoMatch

Missing keys do not satisfy negative predicates.

Trait Implementations

impl Clone for MissingKeyPolicy

fn clone(&self) -> MissingKeyPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MissingKeyPolicy

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

Formats the value using the given formatter.

impl Default for MissingKeyPolicy

fn default() -> MissingKeyPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MissingKeyPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MissingKeyPolicy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
