v0.42.0 (May 13th, 2022)

Breaking Changes:

• ⚠🎉 (aws-sdk-rust#494, aws-sdk-rust#519) The aws_smithy_http::byte_stream::bytestream_util::FsBuilder has been updated to allow for easier creation of
  multi-part requests.

  • FsBuilder::offset is a new method allowing users to specify an offset to start reading a file from.
  • FsBuilder::file_size has been reworked into FsBuilder::length and is now used to specify the amount of data to read.

  With these two methods, it's now simple to create a ByteStream that will read a single "chunk" of a file. The example
  below demonstrates how you could divide a single File into consecutive chunks to create multiple ByteStreams.

  let example_file_path = Path::new("/example.txt");
  let example_file_size = tokio::fs::metadata(&example_file_path).await.unwrap().len();
  let chunks = 6;
  let chunk_size = file_size / chunks;
  let mut byte_streams = Vec::new();
  
  for i in 0..chunks {
      let length = if i == chunks - 1 {
          // If we're on the last chunk, the length to read might be less than a whole chunk.
          // We substract the size of all previous chunks from the total file size to get the
          // size of the final chunk.
          file_size - (i * chunk_size)
      } else {
          chunk_size
      };
  
      let byte_stream = ByteStream::read_from()
          .path(&file_path)
          .offset(i * chunk_size)
          .length(length)
          .build()
          .await?;
  
      byte_streams.push(byte_stream);
  }
  
  for chunk in byte_streams {
      // Make requests to a service
  }
