Struct Panel 

pub struct Panel {
    pub block_hits: Vec<u32>,
    pub cell_hits: Vec<u32>,
    pub running: bool,
    pub pc: u16,
    pub cell: u16,
    pub sp: u16,
    pub hp: u16,
    pub cycles: u32,
}

What one frame of the activity panel shows: the engine’s state at the frame’s snapshot, and the engine clocks each block and each cell ran in the frame before it.

Fields

block_hits: Vec<u32>

One count per engine block (WPE_HW_MAXBLK).

cell_hits: Vec<u32>

One count per program cell (WPE_HW_MAXCELL).

running: bool

pc: u16

cell: u16

sp: u16

hp: u16

cycles: u32

Implementations

impl Panel

pub fn idle() -> Self

The panel before any program: nothing counted, the engine idle.

pub fn pixel(&self, font: &[u8], x: usize, y: usize) -> Option<u16>

The panel’s colour at screen pixel (x, y), or None where the text shows through. Inside its regions:

• the cycle count: ten digit glyphs from the font, PANEL_DIGIT on black, leading zeros black, the units digit always drawn;
• a block tile or cell square: black but for an inner box two pixels in, painted with the HEAT colour of its count, and the box’s one-pixel border PANEL_OUTLINE when the engine is running in it;
• a stack segment: eight pixels wide, a 6 × 10 box one pixel in from the left and three down, lit (PANEL_STACK_LIT) for each frame below sp, else PANEL_GAUGE_UNLIT;
• a heap column: one pixel wide, eight tall from four down, lit (PANEL_HEAP_LIT) below hp.

Trait Implementations

impl Clone for Panel

fn clone(&self) -> Panel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Panel

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

Formats the value using the given formatter.

impl PartialEq for Panel

fn eq(&self, other: &Panel) -> 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.
