Module spacetimedb_table::read_column
source · Expand description
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
.
