Trait CommandArgExtractor

pub trait CommandArgExtractor<Context, Arg>: IsProviderFor<CommandArgExtractorComponent, Context, Arg>
where
    Context: HasCommandArgType,
{
    // Required method
    fn extract_command_arg(
        context: &Context,
        _phantom: PhantomData<Arg>,
    ) -> Context::CommandArg;
}

Required Methods

fn extract_command_arg( context: &Context, _phantom: PhantomData<Arg>, ) -> Context::CommandArg

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.
