Method as_fd

nodedb-bridge/src/eventfd.rs:101–103

Get the raw file descriptor for registration with an event loop. The caller can register this fd with: - Tokio: `AsyncFd::new()` - Glommio: `GlommioDma::from_raw_fd()` or similar - io_uring: `IORING_OP_READ` on the fd

(&self)

    /// - Glommio: `GlommioDma::from_raw_fd()` or similar
    /// - io_uring: `IORING_OP_READ` on the fd
    pub fn as_fd(&self) -> RawFd {
        self.fd.as_raw_fd()
    }
}

// SAFETY: eventfd is a kernel object. The fd can be shared across threads.
