Struct Layout 

pub struct Layout {
    pub font: &'static MonoFont<'static>,
    pub left: i32,
    pub top: i32,
    pub row_pitch: i32,
    pub rows: usize,
    pub size: Size,
    pub battery: BatteryIconMetrics,
    pub overflow: Overflow,
    pub controls: Controls,
}

A board’s panel and controls.

Everything the renderer needs to place a row of text and the battery indicator, plus which gestures to name in the hints. A board picks one of the constants — or writes its own if its panel is neither of the two shapes in the class today — and overrides the fields its hardware disagrees about:

const LAYOUT: Layout = Layout {
    controls: Controls::Dpad,
    ..Layout::OLED_128X64
};

Fields

font: &'static MonoFont<'static>

left: i32

Left margin for row text.

top: i32

Top of row 0’s glyph band.

row_pitch: i32

Distance between the tops of consecutive rows.

rows: usize

How many rows fit on the panel.

size: Size

battery: BatteryIconMetrics

overflow: Overflow

How this panel says a list continues past what it can draw.

controls: Controls

What the user drives it with.

Implementations

impl Layout

pub const OLED_128X64: Self

128×64 OLED: five rows of FONT_6X10. Shared by the Wio Tracker L1’s SH1106 and the Heltec V3’s SSD1306.

pub const EPD_200X200: Self

200×200 e-paper: seven rows of FONT_10X20. The T-Echo’s SSD1681.

pub const fn row_top(&self, row: usize) -> i32

Top of row’s glyph band.

pub fn row_rect(&self, row: usize) -> Rectangle

The full-width band row occupies.

A highlight fills this rather than the glyph cells, so it reads as a solid bar rather than as emphasized text.

pub fn battery_zone(&self) -> Rectangle

The rectangle the battery indicator owns, right-aligned on row 0.

Trait Implementations

impl Clone for Layout

fn clone(&self) -> Layout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Layout

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

Formats the value using the given formatter.

impl Copy for Layout
