함수, 레이아웃 분류

Declare a fixed-length array field inside a uniformStruct field map.

import { arrayOf } from 'typeshade'

시그니처, 설명, 예제는 커밋 c66579bf의 컴파일러 소스에서 그대로 가져온 영어 원문입니다.

구문

function arrayOf<H extends StructHandle>(element: H, count: number): HandleArray<H>;
function arrayOf<T extends ShaderType>(element: T, count: number): TypeArray<T>;

매개변수

element H extends StructHandle: the element: a struct handle, or a shader type.
count number: the array length.

반환값

HandleArray<H>

a HandleArray for a struct handle, a TypeArray for a shader type.

설명

The array is always array<T, N> with a declared count. A runtime-length array<T> is a top-level storageBuffer binding, which takes no count. Which overload applies is decided by the shape of element: a struct handle (from structDecl or ioStruct, recognised by its .of method) returns a HandleArray whose field .at(i) gives the typed field proxy; a bare ShaderType returns a TypeArray whose field .at(i) gives the element read directly.

예제

import { uniformStruct, arrayOf, vec4fT } from 'typeshade'

const U = uniformStruct('Uniforms', { group: 0, binding: 0, as: 'u' }, {
  dash_array: arrayOf(vec4fT, 2),
})
const d0 = U.field.dash_array.at(0) // ReadonlyNode<'vec4<f32>'>
