[−][src]Enum warpgrapher::engine::value::Value

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);
