Trait Commands 

pub trait Commands: Sized {
    // Required methods
    fn parse(
        ctx: &Context,
        command: &ApplicationCommandInteraction,
    ) -> Result<Self, ParseError>;
    fn invoke<'life0, 'life1, 'life2, 'async_trait>(
        &'life0 self,
        ctx: &'life1 Context,
        command_interaction: &'life2 ApplicationCommandInteraction,
    ) -> Pin<Box<dyn Future<Output = Result<(), InvocationError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait,
             'life2: 'async_trait;
}

This trait should be derived for an enum with a variant for each command. This will implement the boilerplate to:

• Parse an interaction into a specific command based on the command name
• Delegate the invocation of a command to the specific enum variant

#[derive(Debug, Commands)]
enum BotCommands {
    Hello(HelloCommand),
}

Required Methods

fn parse( ctx: &Context, command: &ApplicationCommandInteraction, ) -> Result<Self, ParseError>

Parse an interaction into a specific command

fn invoke<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ctx: &'life1 Context, command_interaction: &'life2 ApplicationCommandInteraction, ) -> Pin<Box<dyn Future<Output = Result<(), InvocationError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Invoke the command

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
