Struct unsafe_io::RawHandleOrSocket

pub struct RawHandleOrSocket(_);

A Windows analog for the Posix-ish AsRawFd type. Unlike Posix-ish platforms which have a single type for files and sockets, Windows has distinct types, RawHandle and RawSocket; this type behaves like an enum which can hold either.

It's reasonable to worry that this might be trying too hard to make Windows work like Unix, however in this case, the number of types is small, so the enum is simple and the overhead is relatively low, and the benefit is that we can abstract over major Read and Write resources.

Implementations

impl RawHandleOrSocket

pub fn from_raw_handle(raw_handle: RawHandle) -> Self

Like FromRawHandle::from_raw_handle, but isn't unsafe because it doesn't imply a dereference.

pub fn from_raw_socket(raw_socket: RawSocket) -> Self

Like FromRawSocket::from_raw_socket, but isn't unsafe because it doesn't imply a dereference.

pub fn as_raw_handle(&self) -> Option<RawHandle>

Like AsRawHandle::as_raw_handle, but returns an Option so that it can return None if self doesn't contain a RawHandle.

pub fn as_raw_socket(&self) -> Option<RawSocket>

Like AsRawSocket::as_raw_socket, but returns an Option so that it can return None if self doesn't contain a RawSocket.
