프런트엔드 코드 LAYOUT

A buffer binding's store type breaks one of WGSL's host-shareable rules (§51), which a struct hides from the type map and the backend only meets as emitted text: a bool, alone or in a vector, in a uniform or storage binding, as a field, a runtime array's element or the whole type (type 'bool' cannot be used in address space 'uniform' as it is non-host-shareable, and the same of vec3<bool>), a runtime-sized array<T> that is not its struct's last member, or a runtime-sized array in a uniform, whose type must be constructible.

발생 조건

A buffer binding's store type breaks one of WGSL's host-shareable rules (§51), which a struct hides from the type map and the backend only meets as emitted text: a bool, alone or in a vector, in a uniform or storage binding, as a field, a runtime array's element or the whole type (type 'bool' cannot be used in address space 'uniform' as it is non-host-shareable, and the same of vec3<bool>), a runtime-sized array<T> that is not its struct's last member, or a runtime-sized array in a uniform, whose type must be constructible. Also a two-row matrix (mat2x2, mat3x2, mat4x2) in a uniform, which WGSL and std140 lay out at different offsets (Rule 4.8, surface §40).

예제

example.shade.ts
"use typeshade"
class Uniforms {
on: bool
gain: f32
}
declare const u: uniform<Uniforms>
@fragment
export function main(@location(0) uv: vec2): vec4 {
return vec4(uv * u.gain, 0., 1.)
}

빌드할 때 고정된 컴파일러로 이 프로그램을 컴파일하면 다음 진단이 나옵니다.

TS8051 error, 8행: "Uniforms.on" is a bool; a uniform struct holds numeric scalars only (WGSL's host-shareable rule). Use u32.

이 코드가 적용하는 규칙

규칙 4.8 테스트
Every matCxR with C and R in 2, 3, 4 must be a type, and a square one must also answer to matN.
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.
