Struct RpcError 

pub struct RpcError {
    pub code: RpcErrorCode,
    pub message: String,
    pub daemon_version: Option<String>,
}

Structured RPC failure

Fields

code: RpcErrorCode

Machine-readable code

message: String

Human-readable message (plain English, no theme)

daemon_version: Option<String>

The daemon’s own crate version, when it chose to name it.

Set on a RpcErrorCode::ProtocolMismatch refusal, where it is the only place a client can learn it: the refusal reports the daemon’s PROTOCOL, and HelloAck::daemon_version never arrives. shep daemon reload picks its mechanism by version, and a protocol bump is exactly when that choice matters.

None on every other error, and on any refusal from a daemon built before this field existed — which no upgrade can change, so a reader must treat None as “unknown” and take the conservative path.

Additive by construction: absent on the wire rather than null, and ignored by a client too old to know it, so crate::protocol::PROTOCOL_VERSION does not move for it.
