Struct Runner 

pub struct Runner { /* private fields */ }

REPL runner that manages the line-editor and command registry.

The Runner owns a rustyline::Editor configured with a simple CmdHelper for tab-completion and a Registry of available commands. Construct a Runner with Runner::new() and call run(state) to read a single line of input and dispatch the corresponding command.

Implementations

pub fn new() -> Result<Self>

Construct a new REPL Runner with default command registry and line-editing helper.

Errors

Returns an error if the underlying rustyline::Editor cannot be created.

Returns

A Result containing the newly created Runner.

pub fn run(&mut self, state: &mut State<'_>) -> Result<()>

Read a single line from the user and dispatch the corresponding command.

Arguments

• state - Mutable reference to the runtime State passed to command handlers.

Errors

Returns an error when readline operations fail or when command dispatching returns an error.

Returns
