The current comparisons between an integer type like
i64and aBigIntpromote the
i64to aBigIntthroughBigInt::from.That's pretty inefficient as it causes a memory allocation and deallocation.
This PR fixes this by special casing those comparisons.
Thank you for the great library btw, this has saved my quite some headache ❤️ .
