Enum bolt_proto::value::Value

pub enum Value {
    Boolean(Boolean),
    Integer(Integer),
    Float(Float),
    Bytes(ByteArray),
    List(List),
    Map(Map),
    Null,
    String(String),
    Node(Node),
    Relationship(Relationship),
    Path(Path),
    UnboundRelationship(UnboundRelationship),
    Date(Date),
    Time(Time),
    DateTimeOffset(DateTimeOffset),
    DateTimeZoned(DateTimeZoned),
    LocalTime(LocalTime),
    LocalDateTime(LocalDateTime),
    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).
