With negotiated authentication (CEP-50), nodes may be configured with multiple authenticators. Prior to this change,
a number of areas in the code assumed that there was a single configured authenticator and contained logic that
switched depending on the authenticator type. This logic won't work when multiple authenticators can be configured.
This change eliminates most calls to DataDescriptor.getAuthenticator(), by enabling individual authenticators to
declare the role attributes they support, requiring callers to specify the type of authenticator they're looking
for, and directly returning whether the node can enforce authn or not rather than inferring it by the presence of
an authenticator.
Testing done: Unit tests for auth and config packages; d-tests for auth-related functionality (e.g. ColumnMasks).

The same idea was applied previously in UnfilteredSerializer#serializeRowBody. A state is passed into a consumer function using the existing helper object.

Rust CQL did not have any commits in 9 years. It doesn't even support
protocol V4, and most of the features that a user could expect from the
driver - like load balancing or pagination. No reasonable app would use
it in production.
This commit replaces it with Scylla Rust Driver on the page with
recommended drivers. Scylla Rust Driver is actively developed and
feature-rich. Even though it is primarily developed for Scylla, we do
always make sure it is also compatible with Cassandra and tested with
it.
The original second sentence implied per-table scope, which contradicted
the first sentence. Replaced with explicit keyspace-scope wording and
removed the redundant vector/non-vector qualifier.

Remember that for set and list collections, you need to specify the element type inside the angle brackets (<>). For map, you need to specify both the key type and value type separated by a comma.
The SQL statement you provided for creating a table in Cassandra has a small syntax issue with the comment. In Cassandra, comments should be enclosed in single quotes (') and preceded by the keyword WITH. Additionally, the comment text should be properly formatted
