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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
