Struct Envelope 

pub struct Envelope {
    pub agora_governance_log: u32,
    pub id: GovernanceLogId,
    pub entry_type: GovernanceLogEntryType,
    pub created_at: i64,
    pub prev_hash: Option<Sha256Hex>,
    pub data_hash: Sha256Hex,
}

The fields an entry’s hash commits to

A struct rather than a serde_json::Value so the preimage serializes in declaration order whatever preserve_order says.

Fields

agora_governance_log: u32

Always ENVELOPE_VERSION

id: GovernanceLogId

entry_type: GovernanceLogEntryType

created_at: i64

Unix microseconds — the precision Postgres stores

prev_hash: Option<Sha256Hex>

data_hash: Sha256Hex

Implementations

impl Envelope

pub fn new( id: GovernanceLogId, entry_type: GovernanceLogEntryType, created_at: DateTime<Utc>, prev_hash: Option<Sha256Hex>, data_hash: Sha256Hex, ) -> Self

The version-1 envelope for these fields

pub fn created_at(&self) -> DateTime<Utc>

created_at as a timestamp again

pub fn preimage(&self) -> Vec<u8>

The bytes that are hashed

pub fn entry_hash(&self) -> Sha256Hex

SHA-256 over preimage
