Provides an extension trait ([Close]) for closing I/O related types containing a resource which may return an error when closed.

Provided implementations are for standard library types which implement or contain types which implement:

• IntoRawFd (Unix)

• IntoRawHandle or IntoRawSocket (Windows).

such as File and BufWriter.

Using [Close] enables the handling of I/O errors which might otherwise be ignored during drop.

BufWriter Example

use std::io::{BufWriter, Result, Write};
use io_close::Close;

fn main() -> Result<()> {
let data = "hello world".as_bytes();
let mut buffer = BufWriter::new(tempfile::tempfile()?);
buffer.write_all(data)?;
buffer.close()?;
Ok(())
}
