Subject: [PATCH] Fix compiling net::udp::UdpSocket doctest with Rust 1.71
|
|
|
|
With Rust 1.71 this doctest fails to compile because of a new
|
|
`dropping_copy_types` warning, which is elevated to a hard
|
|
error because of "deny(warnings)".
|
|
|
|
This PR changes the doctest from calling "drop(buffer)"
|
|
to using the "assign to underscore to drop" trick.
