import { Generated } from "https://deno.land/x/typeorm@v0.2.23-rc10/src/index.ts";
Marks a column to generate a value on entity insertion.
There are three types of generation strategy - increment, uuid and rowid (cockroachdb only).
Increment uses a number which increases by one on each insertion.
Uuid generates a special UUID token.
Rowid supports only in CockroachDB and uses unique_rowid()
function
Note, some databases do not support non-primary generation columns.
