Fix Find() with struct-based rows #1917

Closed RReverser closed 3 weeks ago

RReverser commented 3 weeks ago

Description of Changes

Before this, Find() would not return a nullable Row? when Row is a value type (a struct), leading to compilation errors at best and at a struct with all fields set to 0 or null at worst.

This issue was found while updating benchmarks-cs and it's not covered by other modules/* tests, which is why I bundled it with other fixes that make benchmarks-cs compile again in the same PR. I also made a change that ensures that becnhmarks-cs actually compiles in CI (before this, it could only be executed manually).

The fix for this particular issue is in Codegen/Module.cs, while other fixes are removing IndexedAttribute (which shouldn't be exposed to the users) and adding actual indexes to the benchmarks, updating table names, using new .Find / .Filter APIs and such.

Expected complexity level and risk

How complicated do you think these changes are? Grade on a scale from 1 to 5, where 1 is a trivial change, and 5 is a deep-reaching and complex change.

This complexity rating applies not only to the complexity apparent in the diff, but also to its interactions with existing and future code.

If you answered more than a 2, explain what is complex about the PR, and what other components it interacts with in potentially concerning ways.
