구문

interface EntryIoField {
  readonly name: string;
  readonly type: string;
  readonly location?: number;
  readonly builtin?: string;
}

Where the entry spelled it as a member of a struct parameter or struct return, the field is reported flattened out of that struct; see EntryIo.

name읽기 전용 string: The field’s own identifier: a parameter’s name, a flattened struct field’s name, or _ret for a bare non-struct return value (the name the GLSL backend gives that output).
type읽기 전용 string: The DSL type key (the string typeKey returns), the same spelling StructLayout.fields[].type and VertexAttr.type use.
location선택 사항읽기 전용 number: The declared @location(n). Absent on a @builtin field and on an unattributed one; the two are told apart by whether builtin is set.
builtin선택 사항읽기 전용 string: The declared @builtin(name), in WGSL’s own vocabulary (position, vertex_index, …). Builtins are reported alongside locations. A consumer that compares varyings and leaves builtins out (they are not varyings) filters on this field, and can then report that position was excluded because it is a builtin.
