[−][src]Crate io_close
An extension trait (Close
) for closing I/O related types such as
File
and BufWriter
.
Specifically, it is for types containing a resource handle which,
when closed, may return an I/O error.
Provided implementations are for standard library types which implement (or contain types which implement):
-
IntoRawFd
(Unix) -
IntoRawHandle
orIntoRawSocket
(Windows).
Using Close
enables the handling or reporting 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()?; // consume and close buffer and its contained File Ok(()) }
