Struct allegro::shader::Shader

pub struct Shader { /* private fields */ }

A shader program comprising of a pixel (fragment) and a vertex shader. Wraps ALLEGRO_SHADER.

Implementations

impl Shader

pub unsafe fn wrap(shader: *mut ALLEGRO_SHADER) -> Shader

pub fn get_allegro_shader(&self) -> *mut ALLEGRO_SHADER

Return the wrapped Allegro shader pointer.

pub fn attach_shader_source(
    &self,
    shader_type: ShaderType,
    source: Option<&str>
) -> Result<(), String>

Attach a source to the shader. Passing None clears the source.

Returns the log if there was an error.

pub fn attach_shader_source_file(
    &self,
    shader_type: ShaderType,
    filename: &str
) -> Result<(), String>

Attach a source to the shader that is loaded from a file.

Returns the log if there was an error.

pub fn build(&self) -> Result<(), String>

Build the shader. Call this after attaching the sources.

Returns the log if there was an error.

pub fn get_log(&self) -> String

Get the log from the shader. Call this function if any of the attach/build functions fail to determine what went wrong.

pub fn get_platform(&self) -> ShaderPlatform

Return the platform of this shader.

Trait Implementations

impl Drop for Shader

fn drop(&mut self)

Executes the destructor for this type.
