feat(client/dispatch): `TrySendError<T>: std::error::Error`

Open cratelyn opened this issue 4 months ago • 0 comments

this commit introduces a std::error::Error implementation for hyper::client::conn::TrySendError.

this allows callers of hyper::client::conn::http2::SendRequest::try_send_request() or hyper::client::conn::http1::SendRequest::try_send_request() to box a TrySendError<T> without discarding a potentially recovered message.

a std::fmt::Display implementation is added in this commit, because it is a prerequisite for implementations of std::error::Error.
