Enum Level 

pub enum Level {
    Top,
    Settings,
    Bluetooth,
    Gnss,
    Radio,
}

One list in the tree.

A level is a wrapping list of the MenuItems that report it from MenuItem::level. Every level below the top opens from exactly one entry in its parent, which is what lets Back return without a stack.

Implementations

impl Level

pub const ALL: [Level; 5]

The entry in the parent level that opens this one. None for the top level, which nothing opens.

pub const fn back(self) -> Option<MenuItem>

This level’s own Back entry. None for the top level, which has nowhere to go back to.

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Level

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Level

fn eq(&self, other: &Level) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
