Function encode_blob_vec

nodedb-cluster/src/distributed_array/partition.rs:133–139

Encode a `Vec >` (collection of opaque blobs) as a zerompk array. Each blob is emitted as raw msgpack bytes (already encoded by the caller) wrapped in a msgpack bin or str value. We re-encode the entire collection as a msgpack array of byte-arrays so the shard handler can deserialise it as `Vec ` and forward to the engine.

(blobs: &[Vec<u8>])

/// as a msgpack array of byte-arrays so the shard handler can deserialise it
/// as `Vec<raw-bytes>` and forward to the engine.
fn encode_blob_vec(blobs: &[Vec<u8>]) -> Result<Vec<u8>> {
    // zerompk::to_msgpack_vec requires Sized, so pass as a Vec reference.
    let owned: Vec<Vec<u8>> = blobs.to_vec();
    zerompk::to_msgpack_vec(&owned).map_err(|e| ClusterError::Codec {
        detail: format!("partition encode blob vec: {e}"),
    })
}
