Negative size arguments passed to nanoid/non-secure functions are expected to throw a RangeError matching cryptographic nanoid behavior.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

nanoid/non-secure functions return an empty string for negative or non-positive sizes rather than throwing RangeError like root nanoid
assert nanoid() from nanoid/non-secure generates 21-character URL-safe identifiers by default
assert nanoid/non-secure customAlphabet produces IDs restricted to the custom alphabet at requested lengths
assert negative sizes passed to nanoid/non-secure return empty strings while root nanoid throws RangeError
assert float sizes are truncated to integer via bitwise OR and non-numeric sizes evaluate to empty strings
