Struct FaceStack 

pub struct FaceStack {
    pub side: f64,
    pub overlap: f64,
    pub max: usize,
}

How a row of faces is sized: the face’s side, how much each overlaps the one before, and how many faces show before the count badge.

Fields

side: f64

overlap: f64

max: usize

Implementations

impl FaceStack

pub const BAR: FaceStack

The top bar: up to four faces, 24 px, overlapping by 8.

pub const WINDOW: FaceStack

A window’s bar: up to three faces, 20 px.

pub const SMALL: FaceStack

A tab, or a card in the overview: up to three small faces.

pub fn in_face(height: f64) -> FaceStack

The faces standing on a control’s own face height high (a bar’s group of who is here): the ring and the ground around it fit within the control, so no face is cut by the control’s edge.

pub fn group(&self, count: usize) -> (usize, usize)

The faces shown of count people, and the badge standing past them counting the rest: up to three faces, then a “+N” face of its own (four people read as three faces and “+1”, never as a face counting four).

pub fn group_width(&self, count: usize) -> f64

How wide the group of count people is (Self::group), rings included.

pub fn split(&self, count: usize) -> (usize, usize)

The faces shown of count people, and how many the badge counts.

pub fn width(&self, count: usize) -> f64

How wide a stack of count people is, rings included.

pub fn step(&self) -> f64

How far apart two faces stand: their Self::overlap, but never so close that the face drawn over covers the one under past its ring and gap. Each face’s initials are centred in its disc, so the ground of the next face must start past them; otherwise the letters of the earlier face are cut in half (“CO” reading as “C”) and a stack of people stops naming them.

pub fn width_of(&self, shown: usize, more: usize) -> f64

How wide shown faces and a badge counting more are.

pub fn paint( &self, ctx: &mut PaintCtx<'_>, _: (f64, f64), _: (&[Face<'_>], usize), ground: AlphaColor<Srgb>, ) -> (Vec<Rect>, Option<Rect>)

Paint faces (the ones shown, Self::split) and a badge counting more people past them, ending at right, centred on center_y, over ground. Returns each face’s rect (for hit-testing, by index into faces) and the badge’s, if any.

Trait Implementations

impl Clone for FaceStack

fn clone(&self) -> FaceStack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FaceStack

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

Formats the value using the given formatter.

impl PartialEq for FaceStack

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