Trait OutputHandler 

pub trait OutputHandler: Send + Sync {
    // Required method
    fn write(&self, stream: OutputStream, text: &str) -> Result<(), String>;
}

Host-side output handler for Ion’s io::print* functions.

Embedders install an implementation with Engine::set_output or Engine::with_output. The core runtime never writes directly to process stdout/stderr through io::print*.

Required Methods

fn write(&self, stream: OutputStream, text: &str) -> Result<(), String>
