Enum warpgrapher::engine::value::Value [−][src]
pub enum Value { Array(Vec<Value>), Bool(bool), Float64(f64), Int64(i64), Map(HashMap<String, Value>), Null, String(String), UInt64(u64), Uuid(Uuid), }
Intermediate data structure for serialized values, allowing for translation between the values returned by the back-end database (serde_json for Neo4j, 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);
Variants
Bool(bool)
Float64(f64)
Int64(i64)
String(String)
UInt64(u64)
Uuid(Uuid)
Trait Implementations
impl FromInputValue<DefaultScalarValue> for Value
[src]
impl FromInputValue<DefaultScalarValue> for Value
[src]fn from_input_value(v: &InputValue) -> Option<Self>
[src]
fn from_input_value(v: &InputValue) -> Option<Self>
[src]Performs the conversion.
fn from_implicit_null() -> Self
[src]
fn from_implicit_null() -> Self
[src]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
