Struct GlShader

pub struct GlShader {
    pub program_id: GLuint,
    pub gl_context: Rc<dyn Gl>,
}

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)

Executes the destructor for this type.

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for GlShader

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for GlShader

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for GlShader

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

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

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

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