ã DZÍlP üºH E Adapter for [`RawFd`] providing an [`event::Source`] implementation.Á ƒú ü‡E B `SourceFd` enables registering any type with an FD with [`Poll`].Á Íú üÑI F While only implementations for TCP and UDP are provided, Mio supportsÁ ü›N K registering any FD that can be registered with the underlying OS selector.Á üê- * `SourceFd` provides the necessary bridge.Á ˜ú üœL I Note that `SourceFd` takes a `&RawFd`. This is because `SourceFd` **doesÁ üéH E not** take ownership of the FD. Specifically, it will not manage anyÁ ü²P M lifecycle related operations, such as closing the FD on drop.
