Trait CommandProvider 

pub trait CommandProvider: Send + Sync {
    // Required method
    fn command_handlers(&self) -> Vec<Box<dyn CommandHandler>>;
}

Trait for modules that provide command handlers.

Modules implement this trait to register their command handlers. The runner queries this trait during module loading to wire commands.

Design

This trait is separate from the kernel’s Module trait to maintain kernel purity. The kernel defines module identity and lifecycle; command handlers are a driver-layer concern.

Thread Safety

The trait requires Send + Sync because modules may be accessed from multiple threads during command registration and execution.

Example

use reovim_driver_command::{CommandHandler, CommandProvider};

struct EditorModule;

impl CommandProvider for EditorModule {
    fn command_handlers(&self) -> Vec<Box<dyn CommandHandler>> {
        vec![
            Box::new(CursorUp),
            Box::new(CursorDown),
            Box::new(DeleteChar),
        ]
    }
}

Required Methods

fn command_handlers(&self) -> Vec<Box<dyn CommandHandler>>

Get command handlers to register.

Returns boxed handlers that the runner will register in the command registry. Each handler must implement CommandHandler.

Implementation Notes

• Return a fresh Vec each time (handlers are moved into the registry)
• Use Box::new() for each command implementation
• Commands should use CommandId constants from the module’s ids module
