TypeScript - 泛型不匹配

Question

在下面（和附加的）示例中，我试图使用类型为

DeepKeyOf<T>

的泛型来传递嵌套类型遗漏。就其本身而言，

DeepKeyOf<T>

按预期工作，只有当我尝试传递扩展

DeepKeyOf<T>

的泛型时它才不起作用。

下面，我有

MyInterface<TEntity extends IBaseEntity, TOmissions extends DeepKeyOf<TEntity>>

，它试图接受

TOmissions

并将它们传递给

DeepOmittedEntity

。据我所知，我错过了什么？

// https://medium.com/xgeeks/typescript-utility-keyof-nested-object-fa3e457ef2b2
type DeepKeyOf<T> = {
    [Key in keyof T & (string | number)]: T[Key] extends object ? `${Key}` | `${Key}.${DeepKeyOf<T[Key]>}` : `${Key}`
}[keyof T & (string | number)];

// DeepOmit works as expected - https://stackoverflow.com/a/75823617/3329760
type DeepOmit<T, K extends PropertyKey> = {
    [P in keyof T as P extends K ? never : P]: DeepOmit<T[P], K extends `${Exclude<P, symbol>}.${infer R}` ? R : never>
}

// Combining DeepKeyOf and DeepOmit works perfectly!
type DeepOmittedEntity<TEntity extends IBaseEntity, TOmissions extends DeepKeyOf<TEntity>> = DeepOmit<TEntity, "id" | TOmissions>;

interface IBaseEntity {
    id: string;
    more: string;
    other: string;
}

// This works as expected
const someObject: DeepOmittedEntity<IBaseEntity, "more"> = {
    other: "this works"
}

// The add method does not like TOmissions - see linked example
interface MyInterface<TEntity extends IBaseEntity, TOmissions extends DeepKeyOf<TEntity>> {
    add(entities: DeepOmittedEntity<TEntity, TOmissions>[]): void;
}

如果我将

DeepKeyOf<T>

替换为

string

，一切正常，但由于显而易见的原因，智能感知不起作用。
