Struct MaterialColor 

pub struct MaterialColor { /* private fields */ }

A colour ramp: one hue in numbered steps, from the palest (50) to the darkest (900), plus the primary step the family is named after.

Accent ramps carry the four steps 100, 200, 400, 700; the grey ramp carries two extra half-steps (350, 850). That is why the steps are a slice rather than a fixed array — a ramp states which steps it has, and MaterialColor::shade answers None for one it does not.

use frus_core::MaterialColor;

assert_eq!(MaterialColor::RED.shade(300), Some(frus_core::Colors::RED_300));
assert_eq!(MaterialColor::RED.shade(350), None); // only grey has the half-steps
assert_eq!(MaterialColor::GREY.shade(350), Some(frus_core::Colors::GREY_350));

Implementations

impl MaterialColor

pub const fn new( primary: Color, shades: &'static [(u16, Color)], ) -> MaterialColor

Builds a ramp from its primary step and its numbered steps, which must be in ascending order.

pub const fn primary(self) -> Color

The step the family is named after — 500 for a primary ramp, 200 for an accent.

pub fn shade(self, step: u16) -> Option<Color>

The colour at step, or None if this ramp has no such step.

pub fn shade_or_primary(self, step: u16) -> Color

The colour at step, falling back to the primary if the ramp has no such step.

pub fn steps(self) -> impl Iterator<Item = (u16, Color)>

Every (step, colour) pair, in ascending order.

pub fn len(self) -> usize

The number of steps in the ramp.

pub fn is_empty(self) -> bool

Whether the ramp has no steps at all — no bundled family is empty.
