Struct GlShader 

#[repr(C)]
pub struct GlShader {
    pub program_id: GLuint,
    pub gl_context: GlContextPtr,
    pub run_destructor: bool,
}

Fields

program_id: GLuint

gl_context: GlContextPtr

run_destructor: bool

AUDIT: guards against a double-drop deleting the same GL program twice (drop_in_place run twice on a byte-copied struct). Set true on construction; the first drop clears it so a second drop is a no-op.

Implementations

impl GlShader

pub fn new( gl_context: &GlContextPtr, 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.

Errors

Returns an error if the OpenGL implementation has no shader compiler, or if the vertex/fragment shader fails to compile or link.

pub fn draw( shader_program_id: GLuint, texture: &mut Texture, buffers: &[(&VertexBuffer, &[Uniform])], )

Draws vertex buffers, index buffers + uniforms to the texture

Panics

Panics if no framebuffer/depthbuffer was allocated (the GL object lists are empty).

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.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

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, 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

Equality operator ==.

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

Inequality operator !=.

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.
