Trait io_close::Close

pub trait Close: Write {
    pub fn close(self) -> Result<()>;
}

An extension trait for safely dropping I/O writers containing a resource handle.

Required methods

pub fn close(self) -> Result<()>

Drops an I/O writer and closes its contained resource handle (such as a raw file descriptor), ensuring I/O errors resulting from closing this handle are not ignored. The writer is flushed before its handle is closed. If any errors occur during flushing or closing the first such error is returned.
