Type Alias RequireNone<T, K>

Since

1.1.0

Remarks

Explicitly disallows a set of properties by forcing them to never. Useful for mutually exclusive object shapes.

Example

type Test = { a?: string; b?: number; c: boolean };
type Result = RequireNone< Test, 'a' | 'b' >;
// { c: boolean; a?: never; b?: never; }
