Enum IndexClass 

#[non_exhaustive]
pub enum IndexClass {
    Legacy,
    Sai,
    Sasi,
    Custom(String),
}

Which kind of index implementation serves a column.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Legacy

CREATE INDEX without USING: the classic secondary index (equality, CONTAINS).

Sai

Storage-Attached Index, USING 'sai' (Cassandra 5.0): equality, ranges, CONTAINS, vector ANN.

Sasi

SASI, USING '...SASIIndex': equality, ranges and LIKE.

Custom(String)

Any other custom index class; cqlc does not know its capabilities.
