Required Methods

fn has_flag( &self, engine_state: &EngineState, stack: &mut Stack, flag_name: &str ) -> Result<bool, ShellError>

Check if a boolean flag is set (i.e. --bool or --bool=true)

fn get_flag<T: FromValue>( &self, engine_state: &EngineState, stack: &mut Stack, name: &str ) -> Result<Option<T>, ShellError>

fn rest<T: FromValue>( &self, engine_state: &EngineState, stack: &mut Stack, starting_pos: usize ) -> Result<Vec<T>, ShellError>

fn opt<T: FromValue>( &self, engine_state: &EngineState, stack: &mut Stack, pos: usize ) -> Result<Option<T>, ShellError>

fn opt_const<T: FromValue>( &self, working_set: &StateWorkingSet<'_>, pos: usize ) -> Result<Option<T>, ShellError>

fn req<T: FromValue>( &self, engine_state: &EngineState, stack: &mut Stack, pos: usize ) -> Result<T, ShellError>

fn req_parser_info<T: FromValue>( &self, engine_state: &EngineState, stack: &mut Stack, name: &str ) -> Result<T, ShellError>
