Enum ShaderAsset 

pub enum ShaderAsset {
    Path(&'static str),
    Source {
        file_name: &'static str,
        fragment: &'static str,
    },
    Stored(&'static str),
}

Represents a shader asset that can be loaded from a file path, embedded as source, or looked up from the runtime shader storage in [MaterialManager].

Path is loaded from the filesystem at runtime (useful for development/hot-reloading). Source embeds the shader in the binary (via include_str!). Stored references a named entry in the shader storage, enabling runtime-updateable shader code.

Variants

Path(&'static str)

Path to a compiled .glsl file, loaded at runtime

Source

Embedded GLSL ES 3.00 fragment shader source

Fields

file_name: &'static str

Cache key for MaterialManager

fragment: &'static str

GLSL ES 3.00 fragment shader source

Stored(&'static str)

References a named entry in the runtime shader storage.

Implementations

impl ShaderAsset

pub fn fragment_source(&self) -> Cow<'static, str>

Returns the fragment shader source. For Path variant, reads the file synchronously. For Source variant, returns a borrowed reference (zero-copy). For Stored variant, looks up the source from the global shader storage.

pub fn cache_key(&self) -> &str

Returns the cache key used by MaterialManager.

Trait Implementations

impl Clone for ShaderAsset

fn clone(&self) -> ShaderAsset

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ShaderAsset

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
