Miniquad draw pixels

Hello i want to draw pixels to the screen with miniquad.

I want to move them around via rust and then send an array to openGL to just render them. The pixels should have a color and a position. I am fine with having a fixed number of pixels (assuming variable amounts is harder to code/slower). This should be some sort of particle render at the end.

I have done this before using GL_POINTS but this is at least 10 years ago so my opengl is a bit rusty. I remember that i needed all those fragment shaders etc but i can't remember how i put them together to just draw an array of pixels.

I have looked at the examples but they all do already advanced stuff that i have trouble dumping down to my needs.

Also i am having trouble making sense of other 'normal' openGL code tutorials. I just don't know how i would translate them into the miniquad world.

i couldn't find a miniquad tutorial and only found the examples.

can you help me?

i do have code but its a frankenstein from the examples and doesn't even compile right. I would like to not show it and start from scratch. Where can i find help or a tutorial for miniquad?

i am really only interested in drawing pixels of various colors and maybe get some keyboard input.

ok here is my broken code:
It doens't compile at all. i stitched thhis together form the examples but i am lost.

use miniquad::*;

const MAX_PARTICLES:i32 = 1024;

struct Stage {
  ctx: Context,
  pipeline: Pipeline,
  bindings: Bindings,

impl Stage {
  pub fn new(ctx: &mut Context) -> Stage{

    let vertices:&[f32] = &[100.0, 100.0, 100.0];

    let vertex_buffer = Buffer::immutable(ctx, BufferType::VertexBuffer, &vertices);

      let bindings = Bindings {
        vertex_buffers: vec![vertex_buffer],
        images: vec![],

    let shader = Shader::new(ctx, shader::VERTEX, shader::FRAGMENT, shader::meta()).unwrap();

    let pipeline = Pipeline::new(
      &[VertexAttribute::with_buffer("position", VertexFormat::Float3, 0),],

    Stage {
      position: Vec::with_capacity(MAX_PARTICLES),

impl EventHandlerFree for Stage {
  fn update(&mut self) {}

  fn draw(&mut self) {
    //draw pixel array

    //draw ackground gray
    self.ctx.clear(Some((0., 0.1, 0.1, 0.1)), None, None);


fn main() {
        conf::Conf {
            window_title: "Borkele".to_string(),
            window_width: 1024,
            window_height: 768,
            fullscreen: true,
        |ctx| UserData::free(Stage { ctx }),

mod shader {
    use miniquad::*;

    pub const VERTEX: &str = r#"#version 150
    in vec2 position;

    void main() {
        gl_Position = position;

    pub const FRAGMENT: &str = r#"#version 150
    out vec4 color;

    void main() {
        color = vec4(1.0, 1.0, 1.0, 1.0);

    pub fn meta() -> ShaderMeta {
        ShaderMeta {
            images: vec![],
            uniforms: UniformBlockLayout {
                uniforms: vec![],

@MrGloriousFast I think your best bet is to use the quad example from miniquad and strip the uniform bit, the loop, and if you are happy with just one color, the texture.
