Expand description
Intermediate data structure for serialized values, allowing for translation between the values returned by the back-end database (serde_json for cypher-based databases, and a library-specific seralized format for Cosmos and Gremlin DBs), and the serde_json format used to return data to the client.
Examples
let v = Value::Bool(true);

sourceimpl FromInputValue<DefaultScalarValue> for Value
impl FromInputValue<DefaultScalarValue> for Value
sourcefn from_input_value(v: &InputValue) -> Option<Self>
fn from_input_value(v: &InputValue) -> Option<Self>
Performs the conversion.
sourcefn from_implicit_null() -> Self
fn from_implicit_null() -> Self
Performs the conversion from an absent value (e.g. to distinguish between implicit and
explicit null). The default implementation just uses from_input_value
as if an explicit
null were provided. This conversion must not fail. Read more
