Struct app_units::Au

pub struct Au(pub i32);

An App Unit, the fundamental unit of length in Servo. Usually 1/60th of a pixel (see AU_PER_PX)

Please ensure that the values are between MIN_AU and MAX_AU. It is safe to construct invalid Au values, but it may lead to panics and overflows.

Methods

impl Au

pub fn new(value: i32) -> Au

FIXME(pcwalton): Workaround for lack of cross crate inlining of newtype structs!

pub fn scale_by(self, factor: f32) -> Au

pub fn scale_by_trunc(self, factor: f32) -> Au

Scale, but truncate (useful for viewport-relative units)

pub fn from_f64_au(float: f64) -> Self

pub fn from_px(px: i32) -> Au

pub fn to_px(self) -> i32

Rounds this app unit down to the pixel towards zero and returns it.

pub fn ceil_to_px(self) -> i32

Ceil this app unit to the appropriate pixel boundary and return it.

pub fn to_nearest_px(self) -> i32

pub fn to_nearest_pixel(self, pixels_per_px: f32) -> f32

pub fn to_f32_px(self) -> f32

pub fn to_f64_px(self) -> f64

pub fn from_f32_px(px: f32) -> Au

pub fn from_f64_px(px: f64) -> Au

pub fn abs(self) -> Self
