Struct SceneShaderProgram 

pub struct SceneShaderProgram { /* private fields */ }

Backend-independent compiled fragment program. Created by shader extensions; backend pipeline caches belong to the host renderer and its device.

Implementations

impl SceneShaderProgram

pub fn new( wgsl: String, metal: (String, String, String), hlsl: (String, String, String), ) -> Self

Allocate a unique identity for validated backend sources.

pub fn new_with_output_encoding( wgsl: String, metal: (String, String, String), hlsl: (String, String, String), output_encoding: ShaderOutputEncoding, ) -> Self

Create an immutable program with explicit output meaning. Encoding is part of the unique program identity used by backend pipeline caches.

pub fn with_glyph_mask(self) -> Self

Declare that the validated program reads a grayscale glyph atlas at texture binding group 1/binding 0. Call before sharing the program.

pub fn with_path_mask(self) -> Self

Declare a host-provided native path coverage texture at group 1/binding 0.

pub fn uses_path_mask(&self) -> bool

Whether the host must rasterize retained path coverage before this draw.

pub fn uses_glyph_mask(&self) -> bool

Whether each instance requires a retained monochrome atlas tile.

pub fn output_encoding(&self) -> ShaderOutputEncoding

Immutable output meaning; part of this program’s unique cache identity.

pub fn wgsl(&self) -> &str

Immutable validated WGSL source.

pub fn metal(&self) -> &(String, String, String)

Metal source, vertex entry and fragment entry.

pub fn hlsl(&self) -> &(String, String, String)

HLSL source, vertex entry and fragment entry.

pub fn id(&self) -> u64

Stable across clones of an immutable program handle.

Trait Implementations

impl Debug for SceneShaderProgram

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

Formats the value using the given formatter.
