Trait SWrite 

pub trait SWrite {
    // Required methods
    fn swrite_fmt(&mut self, fmt: Arguments<'_>);
    fn swrite_fmt_nl(&mut self, fmt: Arguments<'_>);
}

Implementing this trait allows using the swrite! and swriteln! macros.

Required Methods

fn swrite_fmt(&mut self, fmt: Arguments<'_>)

Write formatted text.

For types implementing std::fmt::Write this is usually done with just a call to std::fmt::Write::write_fmt ignoring the result.

Make sure that write_fmt() never returns Err(_).

fn swrite_fmt_nl(&mut self, fmt: Arguments<'_>)

Write formatted text to the given String, followed by a newline.

For types implementing std::fmt::Write this is usually done with just a call to std::fmt::Write::write_fmt, followed by a type-specific way of appending a newline.

Make sure that write_fmt() never returns Err(_).

Dyn Compatibility

This trait is dyn compatible.

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