Feature coverage

[randy408]

What's still missing:

• [x] Iterator columns that aren't just [inout] or [in]

• [x] An each function for iterating columns that is faster than the current solution

• [x] Traits

• [x] Triggers

• [ ] Full Query API: sorting, etc

• [x] Subqueries - https://github.com/SanderMertens/flecs/issues/258

• [x] Snapshots

• [x] Most functions that take a filter

• [x] All path stuff e.g. ecs.get_fullpath()

• [x] Scopes e.g. ecs.set_scope()

• [x] ecs.array() - flecs-meta does not detect size and alignment fixed: https://github.com/flecs-hub/flecs-meta/pull/17

What's already done:

• [x] Most entity, type functions

• [x] De/serialization (excl. maps)

• [x] Struct, alias components

• [x] Tags

• [x] Prefabs

• [x] Modules

• [x] Systems

• [x] Pipelines and all pipeline funtions

• [x] Singleton API

• [x] Timers

• [x] Logging, tracing, assert API

For consideration:

• More components types?

• Deferred operations?

• Component actions

Features that can't be implemented without threading support:

• Systems that aren't locked to the main thread

• Triggers on host components These are always called on the ecs_progress() thread

• Using script components from the host with a trigger or action callback implemented in Lua same as above
