Struct OverlayColor 

#[repr(transparent)]
pub struct OverlayColor(pub u32);

An overlay colour with real alpha: 0xAA_RR_GG_BB (0xFF = opaque). Used by the overlay-line API (Line3) — the one place in the engine where the high byte genuinely is opacity.

Tuple Fields

0: u32

Implementations

impl OverlayColor

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

Pack an 0xAA_RR_GG_BB word; a is real opacity (0xff = opaque, 0 = invisible).

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

Fully opaque.
