Intro

The below is a breakdown / bird's eye view of how a sparse-array backed ECS like EnTT or Shipyard works.

Please see the thanks and references at the bottom - without their help I would not have been able to share this breakdown with you... everything here is really just notes and rephrasing of what they've written already :)

Also, these notes do not cover archetype systems (like unity) nor adaptations of archetypes (like in Flecs). Though there's a couple comparative footnotes at the end.

Here we go!

Suggestions for Nim v2

Note: this document is a collection of all proposals from the Nim v2 ideas thread. As such, it is/was not by any means reflective of intentions for 2.0: though I've updated this with accepted and implemented proposals.

Breaking changes

Features

• kobi, exelotl, didlybom, solomonthewise, pdkoekfr, snej, apropos: Adopt Options module and make types not nil by default (discussion)
• Zoom, apropos: Overhaul stdlib to work with view types and/or options/results for error handling

Cheap exceptions

Goals:

• Avoid Rust's Option/Either manual error handling strategy.
• Make exceptions cheaper.
• Avoid error translation between Nim libraries by construction. The new vocabulary type ErrorCode is what should be used. Wrappers should translate errors to ErrorCode.
• Make the error out of memory easier to handle.
• Resolve once and for all the "error codes vs exceptions" choice.
