Implementations

impl Program

pub const fn new() -> Program

pub fn load(&mut self, library: &OpenGraphicsLibrary)

impl Program

pub fn create(&self) -> u32

Creates a program object.

Returns 0 if an error occurs creating the program object otherwise returns a non-zero value by which it can be referenced.

pub unsafe fn delete(&self, program_id: u32)

Deletes a program object.

GLError::InvalidValue is generated if program is not a value generated by OpenGL.

pub unsafe fn bind(&self, program_id: u32)

pub unsafe fn attach_shader(&self, program_id: u32, shader_id: u32)

pub unsafe fn link(&self, program_id: u32)

Links a program object.

pub unsafe fn get_parameter(
    &self,
    program_id: u32,
    parameter: ProgramParameter,
    value: &mut i32
)

Returns a parameter from a program object.

pub unsafe fn get_info_log(&self, shader_id: u32, log: &mut String)

Returns the information log for a program object.

Fill log without allocation.

pub unsafe fn get_uniform_location(&self, program_id: u32, name: &str) -> i32

Returns the location of a uniform variable.

name is a null terminated string.

pub unsafe fn get_uniform_block_index(&self, program_id: u32, name: &str) -> u32

Retrieves the index of a named uniform block.

name is a null terminated string.

pub unsafe fn set_uniform_block_binding(
    &self,
    program_id: u32,
    uniform_block_index: u32,
    uniform_block_binding: u32
)

Assigns a binding point to an active uniform block.
