Trait WriteLayered 

pub trait WriteLayered: Write + Bufferable {
    // Required method
    fn close(&mut self) -> Result<()>;

    // Provided method
    fn flush_with_status(&mut self, status: Status) -> Result<()> { ... }
}

An extension of std::io::Write, but adds a close function to allow the stream to be closed and any outstanding errors to be reported, without requiring a sync_all.

Required Methods

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

Flush any buffers and declare the end of the stream. Subsequent writes will fail.

Provided Methods

fn flush_with_status(&mut self, status: Status) -> Result<()>

Like Write::flush, but has a status parameter describing the future of the stream:

• Status::Ok(Activity::Active): do nothing
• Status::Ok(Activity::Push): flush any buffers and transmit all data
• Status::End: flush any buffers and declare the end of the stream

Passing Status::Ok(Activity::Push) makes this behave the same as flush().
