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 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.
