Module spacetimedb_table::read_column

Provides a trait ReadColumn for extracting a single column from a crate::table::RowRef. This is desirable as frequently, e.g. when evaluating filtered queries, we are interested in only a single column (or a small set of columns), and would like to avoid the allocation required by a ProductValue.
