Trait Output 

pub trait Output {
    // Required method
    fn write(&mut self, seg: &str) -> Result<(), IOError>;

    // Provided method
    fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), IOError> { ... }
}

The Output API.

Handlebars uses this trait to define rendered output.

Required Methods

fn write(&mut self, seg: &str) -> Result<(), IOError>

Provided Methods

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), IOError>

Designed to be used with write! macro. for backward compatibility and to avoid breakage the default implementation uses format! this may be not what you want.

Dyn Compatibility

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