Trait Close

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

An extension trait for safely dropping I/O writers.

Required Methods

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

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