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

Array(Vec<Value>)
Bool(bool)
Float64(f64)
Int64(i64)
Null
String(String)
UInt64(u64)
Uuid(Uuid)

Trait Implementations

impl Clone for Value[src]

fn clone(&self) -> Value[src]

Returns a copy of the value. Read more

fn clone_from(&mut self, source: &Self)1.0.0[src]

Performs copy-assignment from source. Read more

impl Debug for Value[src]

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

Formats the value using the given formatter. Read more

fn from(v: String) -> Self[src]

Performs the conversion.

impl From<Uuid> for Value[src]

fn from(v: Uuid) -> Self[src]

Performs the conversion.

impl From<Vec<Value, Global>> for Value[src]

fn from(v: Vec<Value>) -> Self[src]

Performs the conversion.

impl From<bool> for Value[src]

fn from(v: bool) -> Self[src]
