Trait Implementations

impl Menu for ReedlineMenu

fn name(&self) -> &str

Menu name

fn indicator(&self) -> &str

fn is_active(&self) -> bool

Checks if the menu is active

fn menu_event(&mut self, event: MenuEvent)

Selects what type of event happened with the menu

fn can_quick_complete(&self) -> bool

A menu may not be allowed to quick complete because it needs to stay active even with one element

fn can_partially_complete( &mut self, values_updated: bool, editor: &mut Editor, completer: &mut dyn Completer ) -> bool

The completion menu can try to find the common string and replace it in the given line buffer

fn update_values(&mut self, editor: &mut Editor, completer: &mut dyn Completer)

Updates the values presented in the menu This function needs to be defined in the trait because when the menu is activated or the quick_completion option is true, the len of the values is calculated to know if there is only one value so it can be selected immediately

fn update_working_details( &mut self, editor: &mut Editor, completer: &mut dyn Completer, painter: &Painter )

The working details of a menu are values that could change based on the menu conditions before it being printed, such as the number or size of columns, etc. In this function should be defined how the menu event is treated since it is called just before painting the menu

Indicates how to replace in the line buffer the selected value from the menu

fn menu_required_lines(&self, terminal_columns: u16) -> u16
