Exposing the file descriptor in sockets

[ea-ae]

I'd like to utilize the logic inside Socket to connect to a device, but afterwards handle the internal file descriptor manually (lower-level FFI). Currently my only options are either maintaining an internal fork or re-implementing the libc logic that I require.

For example, in the case of bluer::rfcomm::Socket, the internal file descriptor is private.

Would a contribution that'd introduce a pub fn into_fd(self) -> AsyncFd<OwnedFd> into the Socket structs be welcome? Since I don't have too much experience with open source, I thought I'd ask here beforehand. Thank you!

Hi,

into_raw_fd() is public, exactly for this reason. If it does not work, you can consider it a bug and open an issue.

Hope this helps!

However, From<OwnedFd> for Stream and From<Stream> for OwnedFd are currently not implemented. Same for Listener. A PR would be welcome.
