Function close_on_version_error

nodedb-cluster/src/wire_version/handshake_io.rs:162–172

Map a [`WireVersionError`] to a `ClusterError::Transport` with the QUIC connection closed. Helper shared by callers that have already negotiated but encounter a per-frame version mismatch.

(conn: &quinn::Connection, e: WireVersionError)

/// connection closed. Helper shared by callers that have already negotiated
/// but encounter a per-frame version mismatch.
pub fn close_on_version_error(conn: &quinn::Connection, e: WireVersionError) -> ClusterError {
    let reason = e.to_string();
    let reason_bytes = reason.as_bytes();
    conn.close(
        quinn::VarInt::from_u32(0x01),
        &reason_bytes[..reason_bytes.len().min(100)],
    );
    ClusterError::Transport {
        detail: format!("wire version mismatch: {e}"),
