Question: Is the Sender safe to use after it returned an error?

[hrxi]

In trying to solve libp2p/rust-libp2p#2598, it'd be interesting to know whether one can safely continue using a Sender after it returned an error from send_binary_mut, send_ping or send_pong.

Doesn't look like it, the relevant functions use write_all, which cannot track how far it got before an error was returned:

soketto/src/connection.rs

Line 563 in 1c6110e

w.write_all(&header_bytes).await.or(Err(Error::Closed))?;
