Struct PxDensity 

pub struct PxDensity(/* private fields */);

Measurement of pixels in a screen or points in print.

Internally the density is stored as pixels per centimeter.

Trait Implementations

impl Clone for PxDensity

fn clone(&self) -> PxDensity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PxDensity

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

Formats the value using the given formatter.

impl Default for PxDensity

fn default() -> PxDensity

96ppi.

impl<'de> Deserialize<'de> for PxDensity

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PxDensity

"{}" writes {:.0}ppi, "{:#} writes {:.0}ppcm.

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

Formats the value using the given formatter.

impl FromStr for PxDensity

Parses "##", "##unit" and "##.unit()" where ## is a f32 and unit is ppi, dpi or ppcm. When no unit is given assumes DPI.

type Err = ParseFloatError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<PxDensity, <PxDensity as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for PxDensity

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PxDensity

fn cmp(&self, other: &PxDensity) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PxDensity

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

impl PartialOrd for PxDensity

fn partial_cmp(&self, other: &PxDensity) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for PxDensity

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 Transitionable for PxDensity

fn lerp(self, to: &PxDensity, step: Factor) -> PxDensity

Sample the linear interpolation from self -> to by step.

impl Copy for PxDensity
