Struct BackgroundLayer 

pub struct BackgroundLayer { /* private fields */ }

A solid background fill used as the map clear colour.

This is the first small step toward a broader MapLibre-style layer taxonomy: renderers can derive their frame clear colour from the bottom-most scene stack instead of hard-coding a sky colour.

Implementations

impl BackgroundLayer

pub fn new(name: impl Into<String>, color: [f32; 4]) -> Self

Create a new background layer with the given RGBA colour.

pub fn color(&self) -> [f32; 4]

Return the configured RGBA colour.

pub fn set_color(&mut self, color: [f32; 4])

Replace the RGBA colour.

pub fn effective_color(&self) -> [f32; 4]

Return the effective clear colour after applying layer opacity.

Trait Implementations
