Function subsetTypeHasKey

subsetTypeHasKey<
    T,
    SK extends string | number | symbol,
    K extends string | number | symbol,
>(
    object: Pick<T, SK>,
    key: K,
): object is Pick<T, SK | K>
Type guard to check whether the given object (of a subset type constructed from another with Pick and a parameterized key type) has the given key (which is available on the main type T). In other words, reports whether SK extends K.
Type Parameters
- T
- SK extends string | number | symbol
- K extends string | number | symbol
Parameters
- object: Pick<T, SK>
  The object to check.
- key: K
  The key to check for.
Returns object is Pick<T, SK | K>
subsetTypeHasKey<
    T,
    SK extends string | number | symbol,
    K extends string | number | symbol,
>(
    object: Partial<Pick<T, SK>>,
    key: K,
): object is Partial<Pick<T, SK | K>>
Type guard to check whether the given object (of a subset type constructed from another with Partial and Pick and a parameterized key type) has the given key (which is available on the main type T). In other words, reports whether SK extends K.
Type Parameters
- T
- SK extends string | number | symbol
- K extends string | number | symbol
Parameters
- object: Partial<Pick<T, SK>>
  The object to check.
- key: K
  The key to check for.
Returns object is Partial<Pick<T, SK | K>>
