Struct glutin::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

Implementations

impl LogicalSize

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

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

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

Trait Implementations

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 Debug for LogicalSize

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

Formats the value using the given formatter.

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

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

Deserialize this value from the given Serde deserializer.

impl From<(f64, f64)> for LogicalSize

fn from(_: (f64, f64)) -> LogicalSize

Converts to this type from the input type.

impl From<(u32, u32)> for LogicalSize

fn from(_: (u32, u32)) -> LogicalSize

Converts to this type from the input type.

impl Into<(f64, f64)> for LogicalSize

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

Converts this type into the (usually inferred) input type.

impl Into<(u32, u32)> for LogicalSize

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

Note that this rounds instead of truncating.

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: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for LogicalSize

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

Serialize this value into the given Serde serializer.

impl Copy for LogicalSize

impl StructuralPartialEq for LogicalSize
