[−][src]Crate io_close

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:

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(())
}
