Struct style::values::computed::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
