Struct Shader

pub struct Shader {
    pub name: &'static str,
    /* private fields */
}

A program that is run on the GPU.

A Shader contains a Program, that can be bound and run on the GPU using WebGL.

Fields

name: &'static str

A name to refer to the shader with, and for debugging purposes.

Implementations

impl Shader

pub fn new(gl: &GL) -> Self

Create a new Shader Program with default Vertex and Fragment shaders.

pub fn new_with_vertex( gl: &GL, vertex_shader: WebGlShader, name: Option<&'static str>, ) -> Self

Create a new Shader with default Fragment Shader and a custom Vertex Shader.

pub fn create_fragment(gl: &GL, source: &str) -> Result<WebGlShader, String>

Create a fragment WebGlShader.

pub fn create_vertex(gl: &GL, source: &str) -> Result<WebGlShader, String>

Create a vertex WebGlShader.

pub fn create_with_type( gl: &GL, shader_type: ShaderType, source: &str, ) -> Result<WebGlShader, String>

Create a new WebGlShader with a given ShaderType.

pub fn program_with_vertex_and_fragment( gl: &GL, vertex_shader: &WebGlShader, fragment_shader: &WebGlShader, ) -> Result<WebGlProgram, String>

Create a new WebGlProgram with the given vertex and fragment shaders.

pub fn get_uniform_location( &self, gl: &GL, name: &str, ) -> Option<WebGlUniformLocation>

Get the location of a uniform on the Shader.

pub fn get_attrib_location(&self, gl: &GL, name: &str) -> Option<i32>

Get the location of an attribute on the Shader.

Trait Implementations

impl Bind for Shader

fn bind(&self, gl: &GL)

Bind the Shader

fn unbind(&self, gl: &GL)

Optionally unbinds a struct implementing the Bind trait. This effectively resets the WebGL state.

impl Debug for Shader

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

Formats the value using the given formatter.

impl Default for Shader

fn default() -> Self

Returns the “default value” for a type.

impl Display for Shader

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

Formats the value using the given formatter.

impl Drop for Shader

fn drop(&mut self)

Executes the destructor for this type.
