SD0020

In the front end

A "use typeshade" file never reaches this check with the same mistake: the front end refuses it first, under its own code. This program, compiled at build time, gets:

"use typeshade"

class VsOut {
  @builtin("position") pos: vec4
  @location(0) uv: vec2
}

@vertex
export function vs(@builtin("vertex_index") i: u32): VsOut {
  return { pos: vec4(0., 0., 0., 1.), uv: vec2(0., 0.) }
}

@fragment
export function fs(@location(1) uv: vec2): vec4 {
  return vec4(uv, 0., 1.)
}
