Struct Descriptors 

pub struct Descriptors { /* private fields */ }

Available on Unix and crate feature local only.

Descriptors received with UnixConnection::recv_descriptors: up to 64, owned, close-on-exec. Descriptors not taken are closed when this is dropped or reused.

let fds = net_io::Descriptors::new();
assert!(fds.is_empty());
