Enum Value 

pub enum Value {
    Null,
    Bool(bool),
    Int32(i32),
    Int64(i64),
    Float32(f32),
    Float64(f64),
    String(String),
    Bytes(Vec<u8>),
    Timestamp(i64),

    BoolArray(Vec<bool>),
    Int32Array(Vec<i32>),
    Int64Array(Vec<i64>),
    Float32Array(Vec<f32>),
    Float64Array(Vec<f64>),
    StringArray(Vec<String>),
    UuidArray(Vec<[u8; 16]>),
}

A runtime value that can be serialized over the wire.

This enum represents all possible values that can be passed in queries, mutations, and results. It maps to the scalar types defined in the catalog.

Note: Arrays are typed (e.g., BoolArray, Int32Array) to avoid recursive type issues with rkyv serialization.
