    col_ids: &[u8]
) -> Result<(), Errno>
Expand description

Creates an index with the name index_name and type index_type, on a product of the given columns ids in col_ids, identifying columns in the table identified by table_id.

Currently only single-column-indices are supported and they may only be of the btree index type.

Returns an error if

  • a table with the provided table_id doesn’t exist
  • index_type > 1

Traps if index_type == 1 or col_ids.len() != 1.
