| Description |
|
bson crate requires to have a partial ord trait. This will be very tricky when comparing exponents and significands as numbers like `1x10^3` is equal to `1x10^2`. Good example of comparison logic is in the Java Implementation: https://github.com/mongodb/mongo-csharp-driver/blob/v2.8.1/src/MongoDB.Bson/ObjectModel/Decimal128.cs#L1901
