Currently there is no possibility to set up a custom rounding function. Therefore you are limited to the ones that are implemented by default. For my case I need a rounding function that always rounds up (e.g. 0.002 => 0.01 with precision 2, commercial rounding)

It would be nice to pass a callback or a string that describes the rounding mode. If it is a string and the string matches the suppo

Currently they wrap them into pvector which is not as efficient as it could be in Python 3.

Since Cids are already cryptographic-hash-based objects, it makes sense not to do too much extra work hashing them again when used as HashMap/HashSet keys; the hash_hasher crate could be used to improve the performance.

This operations will be used to drop elements in the steam on the right of the given element

var elements = []int{10,12,7,41,5,6}
res:=koazee.StreamOf(elements).DropRight(12).Out().Val()
fmt.Println(res)

// [10,12]
