JSON-serializable expression for query builders.

This enum mirrors the Expression type but uses simple owned types instead of lifetimed Fragments, making it suitable for JSON serialization.

Trait Implementations

impl Clone for JsonExpression

fn clone(&self) -> JsonExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonExpression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JsonExpression

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&Expression> for JsonExpression

fn from(expr: &Expression) -> Self

Converts to this type from the input type.

impl PartialEq for JsonExpression

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<JsonExpression> for Expression

type Error = Error

The type returned in the event of a conversion error.

fn try_from(json: JsonExpression) -> Result<Self>

Performs the conversion.

impl StructuralPartialEq for JsonExpression
