Struct MetaCommandRecord 

pub struct MetaCommandRecord {
    pub format_version: u32,
    pub command: MetaCommand,
}

The versioned envelope payload carrying one MetaCommand (spec section 4.10). Serialized as JSON into a CommandEnvelope stamped with COMMAND_TYPE_META_COMMAND.

Fields

format_version: u32

Format version; see META_COMMAND_FORMAT_VERSION.

command: MetaCommand

The command.

Implementations

impl MetaCommandRecord

pub fn new(command: MetaCommand) -> Self

Wraps command at the current format version.

pub fn encode(&self) -> Result<Vec<u8>, MetaError>

Serializes the record (JSON; human-readable so 128-bit ids take their canonical hex form).

pub fn decode(payload: &[u8]) -> Result<Self, MetaDecodeError>

Parses and verifies a record produced by MetaCommandRecord::encode; v1 records migrate to the canonical shapes (see the module docs). Unknown versions and malformed payloads fail closed.
