//! # Configuration Module
|
|
//!
|
|
//! Holds shared constants for the WSG library — primarily shader paths and embedded WGSL source code.
|
|
//! Centralized here so all submodules import from one place instead of duplicating literal strings.
|
|
//! This enables the PipelineCache to fall back to an embedded default shader when the file-based one is missing.
|
|
//!
|
|
//! ## Interaction with Other Modules
|
|
//! - **pipeline_cache::load_shader()** reads `BASIC_SHADER_PATH` from disk; if unreadable, falls back to `BASIC_SHADER`.
|
|
//! - Both constants are compile-time values (`include_str!`) ensuring the fallback shader is always available even without external files.
|
|
|
|
/// Path to the default WGSL shader file on disk (runtime). Used by PipelineCache::load_shader() for file-based loading.
|
|
pub const BASIC_SHADER_PATH: &str = "assets/shaders/basic_shader.wgsl";
|
|
|
|
/// The basic WGSL shader source code, embedded at compile time via `include_str!`.
|
|
/// Serves as a fallback when `BASIC_SHADER_PATH` cannot be read at runtime.

pub const BASIC_SHADER: &str = include_str!("../assets/shaders/basic_shader.wgsl");
