pub trait LineHandler {
    // Required method
    fn handle_line(&self, line: &str) -> Result<LoopAction, String>;
}

Trait for handling lines read by [LineReader].

Implement this to inject command-execution logic into the REPL loop.

Return values

• Ok(LoopAction::Continue) — prompt for the next line.
• Ok(LoopAction::Break) — exit the loop normally.
• Err(msg) — print the error and continue.

Required Methods

fn handle_line(&self, line: &str) -> Result<LoopAction, String>

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