Function encode_frames 

pub fn encode_frames(ops: &SessionOps, out: &mut Vec<u8>)

Available on crate feature alloc only.

Encodes ops as a single CRC frame, appending it to out.

This is the write-side counterpart of JournalReader: the bytes it produces replay through the reader to reapply every op. The whole batch becomes one frame; the header’s 8-byte length field can address any in-memory batch, so there is no size limit to split around.

Appends nothing if ops is empty.
