Type Alias Const<T>

Const: {
    readonly [K in keyof T]: T[K] extends Function
        ? T[K]
        : T[K] extends any[]
            ? ReadonlyArray<Immutable<T[K][0]>>
            : AsImmutable<T[K]>
}

Makes all fields of the type T as readonly and extends the readonly keyword to all child fields recursively.
