`TS8028`

프런트엔드 코드 ATTRIBUTE_NAME

레지스트리 설명과 컴파일러 메시지는 컴파일러 원문이라 한국어 페이지에서도 영어로 둡니다.

발생 조건

A decorator identifier outside the attribute vocabulary "use typeshade" defines (@vertex, @fragment, @compute, @builtin, @location), e.g. a misspelled @vertx: without this, the decorated function or field just silently stops being an entry point or an I/O field. A WGSL attribute the surface writes another way (@workgroup_size, @size, @group, @binding, @id, @must_use) is named as WGSL's, with where its intent goes; @size anywhere but a field and @align anywhere but a field or a class are named as a struct field's, and @std140 anywhere but a class as not applied; and any decorator nothing reads is refused (Rule 6.7): on a declaration that takes none (a binding, an override, a const or let at any depth, an enum, an interface, a type alias, a namespace, a local function or class, a class expression or a static field), on a constructor, an overload signature, an abstract member, a mixin or an index signature, one that is not a name (@N.k), and one of the list where the place does not apply it (@location on a class, @builtin on a parameter of a function that is not an entry, which Tint refuses).

예제

"use typeshade"

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

빌드할 때 고정된 컴파일러로 이 프로그램을 컴파일하면 다음 진단이 나옵니다.

TS8028 error, 3행: Unknown attribute "@fragmnt". Did you mean "@fragment"?

TS8028 error, 4행: "@location" does not apply to a parameter of a function that is not an entry: it marks an entry's input or output. Remove it.

이 코드가 적용하는 규칙

규칙 6.7 테스트: The attribute names the compiler reads are @vertex, @fragment, @compute, @builtin, @location, @interpolate, @invariant, @blend_src, and @diagnostic (the last four since #168, surface §53 and §54); every other WGSL attribute is either inferred by the compiler or carried as an argument (@compute([64, 1, 1]) carries @workgroup_size), and a decorator outside that list must be refused.
규칙 6.8 테스트: The byte layout the emitted module assumes for a resource and the layout reflect() reports must agree byte for byte, under WGSL’s uniform and storage layout rules, and so must the layout the manifest carries (Rule 11.10); a vertex entry’s vertex buffer is one layout, its @location inputs tightly packed in the order written, which reflect().vertex and the manifest both report.
