Trait CommandHandler 

pub trait CommandHandler: Send + Sync {
    // Required method
    fn execute(&self, args: &str) -> Result<CommandResult>;

    // Provided method
    fn argument_completions(&self, _prefix: &str) -> Vec<AutocompleteItem> { ... }
}

A slash command handler (built-in or extension-provided). Commands use the same Extension trait as tools - built-ins and user extensions register commands through a uniform interface.

Required Methods

fn execute(&self, args: &str) -> Result<CommandResult>

Execute the command with the given arguments string.

Provided Methods

fn argument_completions(&self, _prefix: &str) -> Vec<AutocompleteItem>

Get argument completions for autocomplete. Called when user types /cmd - returns matching autocomplete items.

Dyn Compatibility

This trait is dyn compatible.

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