MapTypes<{iWillBeANumberOneDay: string}, StringToNumber> // gives { iWillBeANumberOneDay: number; } 因为要返回一个新对象,所以我们使用{ [K in keyof T]: ... }的形式描述结果对象。然后就要对 Value 类型进行判断了,为了防止never的作用,我们包一层数组进行判断: ...
Where the chance of cid collision is less than 1 in "the number of atoms in the Universe". If we generated 1 Billion CIDs per second for the next Trillion years there would still be less than a 0.001% chance of collision.3 Tests The tests for this module are a combination of doctests...
