Enum bolt_proto::value::Value

pub enum Value {
    Boolean(bool),
    Integer(i64),
    Float(f64),
    Bytes(Vec<u8>),
    List(Vec<Value>),
    Map(HashMap<String, Value>),
    Null,
    String(String),
    Node(Node),
    Relationship(Relationship),
    Path(Path),
    UnboundRelationship(UnboundRelationship),
    Date(NaiveDate),
    Time(NaiveTime, FixedOffset),
    DateTimeOffset(DateTime<FixedOffset>),
    DateTimeZoned(DateTime<Tz>),
    LocalTime(NaiveTime),
    LocalDateTime(NaiveDateTime),
    Duration(Duration),
    Point2D(Point2D),
    Point3D(Point3D),
}

An enum that can hold values of all Bolt-compatible types.

Conversions are provided for most types, and are usually pretty intuitive (bool to Value::Boolean, i32 to Value::Integer, HashMap to Value::Map, etc.), but some types have no analog in Rust, like a timezone-aware time. For such types, conversions are still provided, but may feel a bit clunky (for example, you can convert a (NaiveTime, impl Offset) tuple into a Value::Time).
