Struct GlslTemplate 

pub struct GlslTemplate {
    pub entry_point: &'static str,
    pub stage: ShaderStage,
    pub glsl: &'static [&'static str],
    pub macros: &'static [GlslMacro],
    pub blocks: &'static [GlslBlock],
    pub textures: &'static [GlslTexture],
    pub varyings: &'static [(&'static str, u32)],
    pub clip_distance_count: u32,
}

GLSL ES of one entry point whose pipeline constants are macros, and the names the backend binds its resources by.

Fields

entry_point: &'static str

stage: ShaderStage

glsl: &'static [&'static str]

The GLSL, in pieces that templates share: the first is the #version line. Each macro’s default is defined under #ifndef, so a definition in front of it wins.

macros: &'static [GlslMacro]

blocks: &'static [GlslBlock]

textures: &'static [GlslTexture]

varyings: &'static [(&'static str, u32)]

Each vertex input or fragment output, by name, with its location.

clip_distance_count: u32

Implementations

impl GlslTemplate

pub fn expand(&self, constants: &PipelineConstants) -> Result<String, String>

The template’s GLSL for a pipeline whose constants are constants: its directives worked out here, so the browser gets only the code the constants keep, with each constant the code reads defined after the #version line. Errors on a value a macro cannot hold and on a directive the template should not have.
