tensorstore::KeyRange::RemovePrefixFromExclusiveMax(
    std::string_view prefix,
    std::string_view exclusive_max);

Returns the exclusive_max bound, relative to prefix, on the set of keys k for which prefix + k < exclusive_max.

If exclusive_max does not start with prefix, returns an empty string (no upper bound). This is only meaningful if prefix < exclusive_max (or exclusive_max is empty), i.e. at least one key starting with prefix is less than exclusive_max; the caller is responsible for handling the case where no such key exists.

For example:

RemovePrefixFromExclusiveMax("a/", "a/d") == "d"
RemovePrefixFromExclusiveMax("a/", "b") == ""
RemovePrefixFromExclusiveMax("a/", "") == ""
