Implementations

impl LchValue

pub fn new(l: f32, c: f32, h: f32) -> Result<LchValue, ValueError>

Returns a result of an LchValue from 3 f32s. Will return Err() if the values are out of range as determined by the Validate trait.

pub fn hue_radians(&self) -> f32

Returns the Hue as radians rather than degrees

Trait Implementations

impl Clone for LchValue

fn clone(&self) -> LchValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LchValue

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

Formats the value using the given formatter.

impl Default for LchValue

fn default() -> LchValue

Returns the “default value” for a type.

fn delta_eq<T: Tolerance>( &self, other: D, method: DEMethod, tolerance: T ) -> bool

Return true if the value is less than or equal to the Tolerance

impl Display for LchValue

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

Formats the value using the given formatter.

impl From<&LabValue> for LchValue

fn from(lab: &LabValue) -> LchValue

Converts to this type from the input type.

impl From<&LchValue> for LabValue

fn from(lch: &LchValue) -> LabValue

Converts to this type from the input type.

impl From<&LchValue> for XyzValue

fn from(lch: &LchValue) -> XyzValue

Converts to this type from the input type.

impl From<&XyzValue> for LchValue

fn from(xyz: &XyzValue) -> LchValue

Converts to this type from the input type.

impl From<LabValue> for LchValue

fn from(lab: LabValue) -> LchValue

Converts to this type from the input type.

impl From<LchValue> for LabValue

fn from(lch: LchValue) -> LabValue

Converts to this type from the input type.

impl From<LchValue> for XyzValue

fn from(lch: LchValue) -> XyzValue

Converts to this type from the input type.

impl From<XyzValue> for LchValue

impl FromStr for LchValue

type Err = ValueError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<LchValue, ValueError>

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

impl PartialEq<LchValue> for LchValue

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