@wjones127 there's a [`try_finish`](https://docs.rs/lz4_flex/latest/lz4_flex/frame/struct.FrameEncoder.html#method.try_finish) method that doesn't consume the `FrameEncoder`. We might be able to do something like this ```rs #[cfg(feature = "lz4")] fn compress_lz4(input: &[u8], output: &mut Vec<u8>, context: &mut CompressionContext) -> Result<(), ArrowError> { use std::io::Write; // assuming CompressionContext having a field called `frame_encoder` of type `FrameEncoder<Vec<u8>>>` context.frame_encoder.encoder.write_all(input)?; encoder.try_finish().map_err(|e| ArrowError::ExternalError(Box::new(e)))?; // copy the bytes from the frame encoder's write buffer let w: &mut Vec<u8> = encoder.get_mut(); output.extend_from_slice(w); // reset the write buffer w.clear(); Ok(()) } ``` -- This is an automated message from the Apache Git Service.
