@larsfillmore Hi, I encounter the same problem. Do you find a work around solution?

@djc Can we use `bytes` crate to dynamically allocate buffer, and shrink to fit after some period? not fixed [u8] for `[MessageDeframer::buf: Box](https://github.com/rustls/rustls/blob/5e9ccd4b5b1154ac4b55316dfad178ba09957069/rustls/src/msgs/deframer.rs#L21)`

@djc I try to use `Vec` to reduce MessageDeframer mem usage, but the memory consumption and performance are worse than @larsfillmore 's implementation.

No, `emit` still return `IllegalActionBeforeOpen` Error. Maybe we should cache the payload when reconnecting, can emit after reconnect.
