Methods

Receiver	Name	Description
`&self`	as_fdio	Borrows the file descriptor as an `FdIo`.
`&self`	borrow	Returns the contained file descriptor.
`&self`	description_flags	Retrieves the file description flags.
`&self`	duplicate	Duplicates the file descriptor.
`&self`	duplicate_as	Duplicates the file descriptor, replacing an existing one.
`&self`	duplicate_min	Duplicates the file descriptor so that the duplicated one has a minimum value.
	from_borrowed	Creates a new borrowed object from a file descriptor.
	from_owned	Creates a new owned object from a file descriptor.
`&self`	is_close_on_exec	Retrieves the status of the `close on exec` flag.
`&self`	is_owned	Returns whether the object owns the file descriptor, i.e., whether it closes it when it goes out of scope.
`&self`	set_close_on_exec	Enables or disables the `close on exec` flag.
`&self`	set_description_flags	Sets the file description flags.
`self`	unwrap	Consumes the object and returns the file descriptor without closing it.
