Struct winit::dpi::LogicalSize

pub struct LogicalSize {
    pub width: f64,
    pub height: f64,
}

A size represented in logical pixels.

The size is stored as floats, so please be careful. Casting floats to integers truncates the fractional part, which can cause noticable issues. To help with that, an Into<(u32, u32)> implementation is provided which does the rounding for you.

Fields

width: f64

height: f64

Methods

impl LogicalSize

pub fn new(width: f64, height: f64) -> Self

pub fn from_physical<T: Into<PhysicalSize>>(
    physical: T,
    dpi_factor: f64
) -> Self

pub fn to_physical(&self, dpi_factor: f64) -> PhysicalSize

Trait Implementations

impl Copy for LogicalSize

impl Clone for LogicalSize

fn clone(&self) -> LogicalSize

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<LogicalSize> for LogicalSize

fn eq(&self, other: &LogicalSize) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &LogicalSize) -> bool

This method tests for !=.

impl From<(f64, f64)> for LogicalSize

fn from((width, height): (f64, f64)) -> Self

Performs the conversion.

impl From<(u32, u32)> for LogicalSize

fn from((width, height): (u32, u32)) -> Self

Performs the conversion.

impl Into<(f64, f64)> for LogicalSize

fn into(self) -> (f64, f64)

Performs the conversion.

impl Into<(u32, u32)> for LogicalSize

fn into(self) -> (u32, u32)

Note that this rounds instead of truncating.

impl Debug for LogicalSize

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LogicalSize

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Serialize for LogicalSize

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
