Implementations

impl Hsla

pub fn to_rgb(self) -> Rgba

pub fn red() -> Self

pub fn green() -> Self

pub fn blue() -> Self

pub fn black() -> Self

pub fn white() -> Self

pub fn transparent_black() -> Self

impl Hsla

pub fn is_transparent(&self) -> bool

Returns true if the HSLA color is fully transparent, false otherwise.

pub fn blend(self, other: Hsla) -> Hsla

Blends other on top of self based on other’s alpha value. The resulting color is a combination of self’s and other’s colors.

If other’s alpha value is 1.0 or greater, other color is fully opaque, thus other is returned as the output color. If other’s alpha value is 0.0 or less, other color is fully transparent, thus self is returned as the output color. Else, the output color is calculated as a blend of self and other based on their weighted alpha values.

Assumptions:

• Alpha values are contained in the range [0, 1], with 1 as fully opaque and 0 as fully transparent.
• The relative contributions of self and other is based on self’s alpha value (self.a) and other’s alpha value (other.a), self contributing self.a * (1.0 - other.a) and other contributing it’s own alpha value.
• RGB color components are contained in the range [0, 1].
• If self and other colors are out of the valid range, the blend operation’s output and behavior is undefined.

pub fn fade_out(&mut self, factor: f32)

Fade out the color by a given factor. This factor should be between 0.0 and 1.0. Where 0.0 will leave the color unchanged, and 1.0 will completely fade out the color.

Trait Implementations

impl Clone for Hsla

fn clone(&self) -> Hsla

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Hsla

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

Formats the value using the given formatter.

impl Default for Hsla

fn default() -> Hsla

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Hsla

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

Deserialize this value from the given Serde deserializer.

impl From<Hsla> for Fill

fn from(color: Hsla) -> Self

Converts to this type from the input type.

impl From<Hsla> for HighlightStyle

fn from(color: Hsla) -> Self

Converts to this type from the input type.

impl From<Hsla> for Rgba

fn from(color: Hsla) -> Self

Converts to this type from the input type.

impl From<Rgba> for Hsla

fn from(color: Rgba) -> Self

Converts to this type from the input type.

impl Ord for Hsla

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Hsla> for Hsla

fn eq(&self, other: &Self) -> 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 PartialOrd<Hsla> for Hsla

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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