Struct Envelope 

pub struct Envelope {
    pub metadata: Metadata,
    pub payload: Payload,
}

Complete transport message.

Fields

metadata: Metadata

Correlation and version metadata.

payload: Payload

Typed payload.

Implementations

impl Envelope

pub fn decode_json(input: &str) -> Result<Self, ProtocolError>

Decodes a JSON envelope against the protocol types.

Transport adapters should use this entry point rather than calling serde_json directly. Unknown keys are rejected. Canonical emit omits skip-optional None; an explicit null on those keys is accepted as absent so accept follows the types instead of a serialize roundtrip.

Errors

Returns ProtocolError for malformed JSON, unknown fields, or failed envelope validation.

pub fn validate(&self) -> Result<(), ProtocolError>

Validates transport-level invariants before dispatch.

Errors

Returns ProtocolError when the major version is unsupported or a required identifier is blank.
