Enum Platform 

pub enum Platform {
    Metal,
    Hlsl,
    Glsl,
}

Shader source language families supported by the engine. Each variant matches one render backend: Metal, HLSL (DirectX), or GLSL (Vulkan).

A given build only ever constructs the variant for its own backend (see current), so the other two read as never-constructed; key still matches all three, so the type stays whole.

Variants

Metal

Metal Shading Language, for the Metal backend.

Hlsl

HLSL, for the DirectX backend.

Glsl

GLSL, for the Vulkan backend.

Implementations

impl Platform

pub fn current() -> Self

The shader platform the current binary’s rendering backend was built for. Resolved from the backend cfg (see build.rs), not the target OS, so a Windows Vulkan build correctly selects GLSL rather than HLSL.

pub fn key(self) -> &'static str

String key used in the sources map of a Shader stage.

pub fn accepts_ext(self, ext: &str) -> bool

Whether a shader source with the given file extension is usable on this platform. The matching extension (metal / hlsl / glsl) is accepted; a non-matching shader extension is rejected so a single-path source authored for one backend doesn’t get fed to another; an unknown extension is accepted by default (the build step surfaces a real compile error later if the file truly can’t be built).

Shared by the per-platform source selection of Shader stages and SdfVolume so both apply identical fallback rules.
