Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Default = 0

Low = 120

Medium = 160

TV = 213

High = 240

XHigh = 320

XXHigh = 480

XXXHigh = 640

Any = 65_534

None = 65_535

Implementations

impl Density

pub fn dpi(self) -> Option<u32>

The DPI associated with the density class. See the Android screen density docs

There are some Density values that have no associated DPI; these values return None.

pub fn approx_hidpi_factor(self) -> Option<f64>

The Hi-DPI factor associated with the density class. This is the factor by which an image/resource should be scaled to match its size across devices. The baseline is a 160dpi screen (i.e., Hi-DPI factor = DPI / 160). See the Android screen density docs

There are some Density values that have no associated DPI; these values return None.

Trait Implementations

impl Clone for Density

fn clone(&self) -> Density

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Density

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

Formats the value using the given formatter.

impl From<Density> for i32

fn from(enum_value: Density) -> Self

Converts to this type from the input type.

impl From<i32> for Density

fn from(number: i32) -> Self

Converts to this type from the input type.

impl FromPrimitive for Density

type Primitive = i32

fn from_primitive(number: Self::Primitive) -> Self

impl PartialEq for Density

fn eq(&self, other: &Density) -> 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 Copy for Density

impl Eq for Density

impl StructuralPartialEq for Density
