    @NonNull Context receiver,
    AttributeSet set,
    @NonNull int[] attrs,
    @AttrRes int defStyleAttr,
    @StyleRes int defStyleRes,
    @NonNull Function1<@NonNull TypedArray, Unit> block
)

Executes block on a TypedArray receiver. The TypedArray holds the attribute values in set that are listed in attrs. In addition, if the given AttributeSet specifies a style class (through the style attribute), that style will be applied on top of the base attributes it defines.

Parameters
`AttributeSet set`	The base set of attribute values.
`@NonNull int[] attrs`	The desired attributes to be retrieved. These attribute IDs must be sorted in ascending order.
`@AttrRes int defStyleAttr`	An attribute in the current theme that contains a reference to a style resource that supplies defaults values for the `TypedArray`. Can be 0 to not look for defaults.
`@StyleRes int defStyleRes`	A resource identifier of a style resource that supplies default values for the `TypedArray`, used only if `defStyleAttr` is 0 or can not be found in the theme. Can be 0 to not look for defaults.
`@NonNull Function1<@NonNull TypedArray, Unit> block`	The block that will be executed.
