Enum Size

pub enum Size {
    Pixel(i32),
    Ratio(f32),
}

Helper enum to represent a size which can be an absolute pixel value or a relative ratio value

Variants

Pixel(i32)

Size in pixels (ie. 10 means 10 pixels)

Ratio(f32)

Relative size as a ratio between 0 to 1 (ie. 0.5 means 50%)

Implementations

impl Size

pub fn into_absolute(self, whole: u32) -> i32

Turn the size into an absolute value.

A pixel value will be returned as is, a ratio value will be multiplied by the provided whole to calculate the absolute value.

Hint

A negative ratio value will be converted into an absolute number before being applied.

Trait Implementations

impl Clone for Size

fn clone(&self) -> Size

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Size

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Size

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Size

fn eq(&self, other: &Size) -> 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 Serialize for Size

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Size

impl StructuralPartialEq for Size
