Struct ControlObjectEnvelope 

pub struct ControlObjectEnvelope<T> {
    pub kind: ControlObjectKind,
    pub format_version: u32,
    pub payload_checksum: String,
    pub state: T,
}

In-memory view of a control object envelope.

This struct is not the durable layout; durable bytes are produced only by encode_control_object and validated only by decode_control_object.

Fields

kind: ControlObjectKind

Durable-family discriminator that selects T and its independent version.

format_version: u32

Family-local format version obtained from kind.

payload_checksum: String

Digest of the payload JSON exactly as stored in the durable document, in sha256:<hex> form.

state: T

Decoded control state protected by payload_checksum.

Implementations

impl<T> ControlObjectEnvelope<T>

where T: Serialize,

pub fn from_state( kind: ControlObjectKind, state: T, ) -> Result<Self, EnvelopeCodecError>

Builds a family-versioned envelope and computes its checksum from canonical state JSON.

Construction fails when state cannot be encoded.
