Implementations§

Source§

impl CollectionOperationEvaluator

Source

pub fn eval_subscript_access( collection: &Value, index: &Value, ) -> Result<Value, ExpressionError>

Index access for evaluation

Source

pub fn eval_range_access( collection: &Value, start: Option<&Value>, end: Option<&Value>, ) -> Result<Value, ExpressionError>

Access to the evaluation range

Source

pub fn eval_property_access( object: &Value, property: &str, ) -> Result<Value, ExpressionError>

Access to the evaluation attribute

Source

pub fn eval_attribute_access( object: &Value, attribute: &Value, ) -> Result<Value, ExpressionError>

Access to evaluation attributes (Attribute operations, used for BinaryOperator::Attribute) Format the value on the right side as a string and use it as the attribute name.

Source

pub fn eval_struct_field_access( object: &Value, field: &str, ) -> Result<Value, ExpressionError>

STRUCT field access (e.g. addr.city).

Resolves a named field of a STRUCT value; missing fields yield NULL. Vertex/Edge/Map bases fall back to property-access semantics so tag-qualified paths such as $$.Person.name resolve correctly.
