}

Fields

program_id: GLuint

gl_context: Rc<dyn Gl>

Implementations

impl GlShader

pub fn new(
    gl_context: Rc<dyn Gl>,
    vertex_shader: &str,
    fragment_shader: &str
) -> Result<Self, GlShaderCreateError>

Compiles and creates a new OpenGL shader, created from a vertex and a fragment shader string.

If the shader fails to compile, the shader object gets automatically deleted, no cleanup necessary.

pub fn draw<T: VertexLayoutDescription>(
    &mut self,
    buffers: &[(Rc<VertexBuffer<T>>, Vec<Uniform>)],
    clear_color: Option<ColorU>,
    texture_size: LogicalSize
) -> Texture

Draws vertex buffers, index buffers + uniforms to the currently bound framebuffer

NOTE: FrameBuffer::bind() and VertexBuffer::bind() have to be called first!

Trait Implementations

impl Debug for GlShader

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

Formats the value using the given formatter.

impl Display for GlShader

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

Formats the value using the given formatter.

impl Drop for GlShader

fn drop(&mut self)

impl Eq for GlShader

impl Hash for GlShader

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,

impl Ord for GlShader

fn cmp(&self, other: &Self) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<GlShader> for GlShader

fn eq(&self, other: &GlShader) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<GlShader> for GlShader

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
