Struct RectEdge 

pub struct RectEdge {
    pub x: Option<WindowEdge>,
    pub y: Option<WindowEdge>,
}

The edge of a free rect (a floating window, a picture in a document) that a drag grabbed: which side of each axis moves. Absent on an axis the edge leaves alone, so a side edge moves one axis and a corner both.

Fields

x: Option<WindowEdge>

y: Option<WindowEdge>

Implementations

impl RectEdge

pub fn at(rect: Rect, p: Point, grip: f64, top_band: f64) -> Option<RectEdge>

The sides a pointer grip px from rect’s edges grabs, or None off every edge. top_band is the height at the top of the rect that drags the rect instead of resizing it (a title bar), so no side edge is offered there; the bottom edge is everywhere along the width.

pub fn resize(self, rect: Rect, by: Vec2, minimum: Size) -> Rect

rect after this edge was carried by: each grabbed side follows the pointer and its opposite side holds still, down to minimum on each axis.

Trait Implementations

impl Clone for RectEdge

fn clone(&self) -> RectEdge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RectEdge

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

Formats the value using the given formatter.

impl PartialEq for RectEdge

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