std::os::unix::io::IntoRawFd - Rust
Description: API documentation for the Rust `IntoRawFd` trait in crate `std`.
Keywords: rust, rustlang, rust-lang, IntoRawFd

# 1.4.0[−][src]Trait std::os::unix::io::IntoRawFd

    pub trait IntoRawFd {
        fn into_raw_fd(self) -> RawFd;
    }

This is supported on Unix only.

A trait to express the ability to consume an object and acquire ownership of its raw file descriptor.

## Required methods

### `fn into_raw_fd(self) -> RawFd`

Consumes this object, returning the raw underlying file descriptor.

This function transfers ownership of the underlying file descriptor to the caller. Callers are then the unique owners of the file descriptor and must close the descriptor once it's no longer needed.

# Example

    use std::fs::File;
    use std::os::unix::io::{IntoRawFd, RawFd};

    let f = File::open("foo.txt")?;
    let raw_fd: RawFd = f.into_raw_fd();
