Implementations

impl<'r, 'a> CommandBuilder<'r, 'a>

pub fn description(self, desc: &str) -> Self

Sets the command description (shown in /help).

pub fn arg(self, name: &str, arg_type: Arg) -> Self

Adds a required argument with default validation.

pub fn arg_with(self, name: &str, arg_type: Arg, validation: Validation) -> Self

Adds a required argument with custom validation.

pub fn optional_arg(self, name: &str, arg_type: Arg) -> Self

Adds an optional argument with default validation.

pub fn variant( self, build: impl FnOnce(VariantBuilder) -> VariantBuilder, ) -> Self

Adds a variant for polymorphic commands.

Each variant is a separate argument list. The parser tries variants in order and uses the first one that succeeds.

pub fn handler( self, handler: impl Fn(&CommandArgs, &dyn Context) + Send + Sync + 'static, )

Sets the handler and registers the command.
