Struct Envelope 

pub struct Envelope {
    pub v: u32,
    pub kind: String,
    pub id: String,
    pub seq: u64,
    pub ts: u64,
    pub instance: String,
    pub hash: Option<String>,
    pub state: Value,
}

A versioned store record: state is the kind-specific payload; a tombstone carries state: null.

Fields

v: u32

kind: String

id: String

seq: u64

ts: u64

Unix ms.

instance: String

hash: Option<String>

state: Value
