OwnedFd in std::os::fd - Rust

pub struct OwnedFd {  }

An owned file descriptor.

This closes the file descriptor on drop. It is guaranteed that nobody else will close the file descriptor.

This uses repr(transparent) and has the representation of a host file descriptor, so it can be used in FFI in places where a file descriptor is passed as a consumed argument or returned as an owned value, and it never has the value -1.

You can use AsFd::as_fd to obtain a BorrowedFd.

Creates a new OwnedFd instance that shares the same underlying file description as the existing OwnedFd instance.

Takes ownership of a File’s underlying file descriptor.

Creates a ChildStderr from the provided OwnedFd.

The provided file descriptor must point to a pipe with the CLOEXEC flag set.

Converts to this type from the input type.
