Struct norad::Color

pub struct Color { /* private fields */ }

A color in RGBA (Red-Green-Blue-Alpha) format.

See https://unifiedfontobject.org/versions/ufo3/conventions/#colors.

Implementations

impl Color

pub fn to_rgba_string(&self) -> String

Serializes the color into a string as defined by the UFO specification. Precision is limited to three decimal places, which is enough to losslessly roundtrip to colors represented by u8 tuples.

impl Color

pub fn new( red: f64, green: f64, blue: f64, alpha: f64 ) -> Result<Self, ColorError>

Create a color with RGBA values in the range 0..=1.0.

Returns an error if any of the provided values are not in the allowed range.

pub fn channels(&self) -> (f64, f64, f64, f64)

Returns the RGBA channel values.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Color

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Color

fn deserialize<D>(deserializer: D) -> Result<Color, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for Color

type Err = ColorError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl PartialEq for Color

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

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
