A list of bytes::Bytes chunks.
This crate provides a BufList type that is a list of Bytes chunks.
The type implements bytes::Buf, so it can be used in any APIs that use Buf.
The main use case for BufList is to buffer data received as a stream of chunks without
having to copy them into a single contiguous chunk of memory. The BufList can then be passed
into any APIs that accept Buf.
If you've ever wanted a Vec<Bytes> or a VecDeque<Bytes>, this type is for you.
Gather chunks into a BufList, then write them all out to standard error in one go:
```rust use buf_list::BufList; use tokio::io::AsyncWriteExt;
async fn main() { let mut buflist = BufList::new(); buflist.pushchunk(&b"hello"[..]); buflist.pushchunk(&b"world"[..]); buflist.push_chunk(&b"!"[..]);
let mut stderr = tokio::io::stderr();
stderr.write_all_buf(&mut buf_list).await.unwrap();
} ```
