Trait Write 

pub trait Write {
    // Required methods
    fn write(&mut self, buf: &[u8]) -> Result<usize>;
    fn flush(&mut self) -> Result<()>;

    // Provided method
    fn write_all(&mut self, buf: &[u8]) -> Result<()> { ... }
}

A generic trait describing an output stream.

See std::io::Write for more information.

Required Methods

fn write(&mut self, buf: &[u8]) -> Result<usize>

Writes buf into this writer, returning how many bytes were written.

Errors

If an I/O error occurs while writing to the underlying writer.

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

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

Errors

If an I/O error occurs while flushing the underlying writer.

Provided Methods

fn write_all(&mut self, buf: &[u8]) -> Result<()>

Attempts to write an entire buffer into this writer.

Errors

If an I/O error occurs while writing to the underlying writer.

Dyn Compatibility

This trait is dyn compatible.

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