Struct EnvelopeCodec 

pub struct EnvelopeCodec;

Envelope encode + decode helper. Stateless; thin façade over prost’s Message::encode_to_vec / Message::decode.

Implementations

impl EnvelopeCodec

pub fn encode(env: &WireEnvelope) -> Vec<u8>

Encode env to a prost wire-format byte vector.

Callers must stamp ENVELOPE_SCHEMA_VERSION on the envelope before encode; production paths land it on push into OutboundQueue::push so this function avoids cloning the (potentially large) payload bytes solely to set one u32.

pub fn decode_capped( bytes: &[u8], caps: &EnvelopeCaps, ) -> Result<WireEnvelope, EnvelopeDecodeError>

Bounded decode — the only inbound decode entry. Rejects the buffer at the length / fill-count / schema-version layer BEFORE prost allocation, so an adversarial sender can’t pre-balloon memory by advertising large lengths in the protobuf header.
