Implementations

impl ThemeColor

pub const fn rgba(r: u8, g: u8, b: u8, a: u8) -> Self

Construct from individual sRGB channels and alpha.

pub const fn rgb(r: u8, g: u8, b: u8) -> Self

Construct an opaque colour from sRGB channels.

pub const fn r(self) -> u8

Red channel.

pub const fn g(self) -> u8

Green channel.

pub const fn b(self) -> u8

Blue channel.

pub const fn a(self) -> u8

Alpha channel (0xFF = fully opaque).

pub const fn is_opaque(self) -> bool

true when the colour is fully opaque.

pub fn as_hex(self) -> String

Stable #rrggbbaa lowercase hex token used in serialisation.

pub fn from_hex(token: &str) -> Option<Self>

Parse a #rrggbb (opaque) or #rrggbbaa hex token.

Trait Implementations

impl Clone for ThemeColor

fn clone(&self) -> ThemeColor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ThemeColor

impl Debug for ThemeColor

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

Formats the value using the given formatter.

impl Eq for ThemeColor

impl Hash for ThemeColor

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ThemeColor

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