[I] Support halve and decay for CountMinSketch (datasketches-rust)
tisonkun opened a new issue, #70:
URL: https://github.com/apache/datasketches-rust/issues/70
Ref -
* https://docs.rs/cmsketch/latest/cmsketch/struct.CMSketchU16.html
While migrating @mrcroxx's foyer from CMSketch to DataSketches' CountMinSketch, I noticed this gap.
Our implementation was initialized at:
* https://github.com/apache/datasketches-rust/pull/38
* https://github.com/apache/datasketches-java/issues/494
* https://github.com/apache/datasketches-go/pull/42
* https://github.com/apache/datasketches-cpp/pull/325
I wonder if `halve` and `decay` are part of the standard CountMin sketch and how we can implement it into datasketches-rust.
