Struct PixelGrid 

pub struct PixelGrid {
    pub device_px: f64,
    pub nudge_x: f64,
    pub nudge_y: f64,
}

One device pixel in CSS pixels, and the nudge that puts an element’s content on the device-pixel grid.

Fields

device_px: f64

One device pixel, in CSS pixels (1 / devicePixelRatio).

nudge_x: f64

How far right, in CSS pixels, the element’s content must move for its left edge to land on a device pixel: at least 0 and under one device pixel.

nudge_y: f64

How far down, likewise, for its top edge.

Implementations

impl PixelGrid

pub const UNMEASURED: PixelGrid

The grid assumed where there is no window to measure (the server render): CSS pixels, no nudge.

pub const ON_GRID: f64 = 1e-3

A corner closer than this to a device pixel’s edge, in device pixels, is on it. Layout keeps positions in its own units, so a corner meant for a grid line can land a hair past it, and a nudge of almost a whole pixel would only shift the content.

pub fn at(ratio: f64, left: f64, top: f64) -> PixelGrid

The grid at device pixel ratio ratio under a box whose top-left corner sits at (left, top) CSS pixels in the viewport.

Trait Implementations

impl Clone for PixelGrid

fn clone(&self) -> PixelGrid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PixelGrid

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

Formats the value using the given formatter.

impl PartialEq for PixelGrid

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