Trait orkhon::prelude::ops::nn::tract_downcast_rs::__std::os::unix::io::AsRawFd 1.0.0[−][src]
This is supported on Unix only.
A trait to extract the raw unix file descriptor from an underlying object.
This is only available on unix platforms and must be imported in order
to call the method. Windows platforms have a corresponding AsRawHandle
and AsRawSocket set of traits.
Required methods
pub fn as_raw_fd(&self) -> i32[src]
Extracts the raw file descriptor.
This method does not pass ownership of the raw file descriptor to the caller. The descriptor is only guaranteed to be valid while the original object has not yet been destroyed.
Example
use std::fs::File; use std::os::unix::io::{AsRawFd, RawFd}; let mut f = File::open("foo.txt")?; // Note that `raw_fd` is only valid as long as `f` exists. let raw_fd: RawFd = f.as_raw_fd();
