Struct BufferProgress

pub(crate) struct BufferProgress {
    processed: usize,
    discard: usize,
}

Accounting structure tracking progress in parsing a single buffer.

Fields

processed: usize

Prefix of the buffer that has been processed so far.

processed may exceed discard, that means we have parsed some buffer, but are still using it. This happens due to in-place decryption of incoming records, and in-place reassembly of handshake messages.

0 <= processed <= len

discard: usize

Prefix of the buffer that can be removed.

If discard exceeds processed, that means we are ignoring data without processing it.

0 <= discard <= len
