pub async fn read_line_capped<R>(
reader: &mut R,
max_bytes: usize,
) -> Result<CappedLine>where
R: AsyncBufRead + Unpin,Expand description
Read one newline-delimited line from reader, refusing to buffer more than
max_bytes before the newline.
Unlike AsyncBufReadExt::read_line/lines(), a peer that streams bytes
without ever sending \n cannot drive unbounded allocation here: once the
pending line passes max_bytes the buffered bytes are dropped and we only
scan forward for the next newline to resync.
