Difference between KeyRange and KeySlice in astayanx APIs

What is the difference between KeyRange and KeySlice APIs in Astyanax?

Based on the Astyanax documentation, it looks like getKeyRange retrieves data based on a range of two keys. Essentially, this is equivalent of a key-based greater-than/less-than query.

Additionally, getKeySlice retrieves data based on a specific list of (non-contiguous) keys. This would be equivalent to querying for data having a key present IN the list.

Their GitHub "Getting Started" page has an example of how to use getKeySlice under "Reading a set of non-contiguous rows."

OperationResult<Rows<String, String>> result =
  ks.prepareQuery(CF_STANDARD1)
    .getKeySlice("Key1", "Key2", "Key3")
    .execute();
