Struct Program 

pub struct Program {
    pub uniforms: UniformList,
    /* private fields */
}

A shader program and its uniforms.

Cloning a program creates a new program, referencing the internal shaders of the source program but using its own copy of the uniforms.

Fields

uniforms: UniformList

Implementations

impl Program

pub fn from_file(context: &Context, file: &str) -> Result<Self>

Creates a program from a fragment shader file.

pub fn from_string(context: &Context, source: &str) -> Result<Self>

Creates a program from a WGSL fragment shader string.

If the shader does not already declare its own bindings (@group(0) @binding), the engine automatically prepends the appropriate preamble, which provides sheet(), sheetSize(), sheetComponent(), and the input struct.

For texture shaders (postprocessors, fills): write @fragment fn main(input: TextureFragmentInput). For sprite shaders (layers): write @fragment fn main(input: SpriteFragmentInput).

pub fn set_uniform<T>(&mut self, name: &str, value: &T)

where T: AsUniform,

Sets a uniform value by name.

pub fn remove_uniform<T>(&mut self, name: &str) -> bool

Removes a uniform value by name.

Trait Implementations

impl Clone for Program

fn clone(&self) -> Program

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Program

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

Formats the value using the given formatter.
