Struct Menus 

pub struct Menus { /* private fields */ }

The built-in menus of one ROM, by menu number.

Implementations

impl Menus

pub fn len(&self) -> usize

The highest menu number plus one.

pub fn truncated(&self) -> bool

Whether the read stopped at MAX_STEPS (garbage, or a ROM far larger than any known): the result is incomplete.

pub fn is_empty(&self) -> bool

Whether no menu was found.

pub fn get(&self, n: u32) -> Option<&MenuDef>

Menu n’s definition.

pub fn number(&self, pointer: u32, mem: &dyn Memory) -> Option<u32>

The menu a current-menu pointer (Layout::menu_ptr) designates: pointer is that pointer’s value and mem the machine, which holds either the definition itself (48SX) or an XLIB name of the menu library’s entry (48GX, 49G).

pub fn iter(&self) -> impl Iterator<Item = (u32, &MenuDef)>

The menus with a definition: (number, definition).

pub fn paths(&self, roots: &[(u32, String)]) -> BTreeMap<u32, String>

Each menu’s name: a root menu’s from roots (the keyboard legend of the key that opens it), a submenu’s as its parent’s name and the label of the key that leads to it (MTH HYP), the shortest path winning. A menu no key reaches is named as the calculator opens it, MENU n, and its submenus after it (MENU 62 FMT).

pub fn placement( &self, paths: &BTreeMap<u32, String>, ) -> BTreeMap<String, Vec<String>>

For each command, the names of the menus that offer it (in menu number order), named by paths.
