ColorOps

Struct ColorOps

pub struct ColorOps;

Expand description

Zero-sized type that hosts color utility functions.

All methods are static (no self receiver) and are used by the #[goud_api] proc-macro to auto-generate #[no_mangle] extern "C" FFI wrappers.

Implementations§

impl ColorOps

pub fn white() -> FfiColor

Returns the white color constant.

pub fn black() -> FfiColor

Returns the black color constant.

pub fn red() -> FfiColor

Returns the red color constant.

pub fn green() -> FfiColor

Returns the green color constant.

pub fn blue() -> FfiColor

Returns the blue color constant.

pub fn yellow() -> FfiColor

Returns the yellow color constant.

pub fn transparent() -> FfiColor

Returns the transparent color constant.

pub fn rgba(r: f32, g: f32, b: f32, a: f32) -> FfiColor

Creates a color from RGBA components.

pub fn rgb(r: f32, g: f32, b: f32) -> FfiColor

Creates a color from RGB components with alpha = 1.0.

pub fn from_u8(r: u8, g: u8, b: u8, a: u8) -> FfiColor

Creates a color from 8-bit RGBA values (0-255).

pub fn from_hex(hex: u32) -> FfiColor

Creates a color from a hex value (0xRRGGBB or 0xRRGGBBAA).

pub fn lerp(from: FfiColor, to: FfiColor, t: f32) -> FfiColor

Linearly interpolates between two colors.

pub fn with_alpha(color: FfiColor, alpha: f32) -> FfiColor

Returns a new color with the specified alpha.
