    "title": "reject_remote_clients Configuration corruption",
    "summary": "On Windows, configuring a named pipe server with [pipe_mode] will force [ServerOptions]::[reject_remote_clients] as `false`. This drops any intended explicit configuration for the [reject_remote_clients] that may have been set as `true` previously. The default setting of [reject_remote_clients] is normally `true` meaning the default is also overridden as `false`. ## Workarounds Ensure that [pipe_mode] is set first after initializing a [ServerOptions]. For example: ```rust let mut opts = ServerOptions::new(); opts.pipe_mode(PipeMode::Message); opts.reject_remote_clients(true); ``` [ServerOptions]: https://docs.rs/tokio/latest/tokio/net/windows/named_pipe/struct.ServerOptions.html [pipe_mode]: https://docs.rs/tokio/latest/tokio/net/windows/named_pipe/struct.ServerOptions.html#method.pipe_mode [reject_remote_clients]: https://docs.rs/tokio/latest/tokio/net/windows/named_pipe/struct.ServerOptions.html#method.reject_remote_clients",
