Variants

Tag

Tag expression.

Evaluates to resolver items where the tag is present.

Fields

Field

Key/Value expression.

Evaluates to resolver items where the given field/value pair is present.

Fields

key: String

value: FieldValue

HasField

HasField expression.

Evaluates to resolver items where the given field is present.

Fields

key: String

And

And expression.

Evaluates to the intersection of its two sub-expressions.

Fields

and: (Box<RawExpression>, Box<RawExpression>)

Or

Or expression. Evaluates to the union of its two sub-expressions.

Trait Implementations

impl Clone for RawExpression

fn clone(&self) -> RawExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RawExpression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RawExpression

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for RawExpression

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 RawExpression

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<RawExpression> for Expression<ExpressionField>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: RawExpression) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for RawExpression

impl StructuralPartialEq for RawExpression
