This updates the `pipelined-rendering` branch to use the latest `bevy_ecs` from `main`. This accomplishes a couple of goals: 1. prepares for upcoming `custom-shaders` branch changes, which were what drove many of the recent bevy_ecs changes on `main` 2. prepares for the soon-to-happen merge of `pipelined-rendering` into `main`. By including bevy_ecs changes now, we make that merge simpler / easier to review. I split this up into 3 commits: 1. **add upstream bevy_ecs**: please don't bother reviewing this content. it has already received thorough review on `main` and is a literal copy/paste of the relevant folders (the old folders were deleted so the directories are literally exactly the same as `main`). 2. **support manual buffer application in stages**: this is used to enable the Extract step. we've already reviewed this once on the `pipelined-rendering` branch, but its worth looking at one more time in the new context of (1). 3. **support manual archetype updates in QueryState**: same situation as (2).

|
|
|
|
// by default, trace and debug logs are ignored because they are "noisy"
|
|
// you can control what level is logged by adding the LogSettings resource
|
|
// alternatively you can set the log level via the RUST_LOG=LEVEL environment variable
|
|
// ex: RUST_LOG=trace, RUST_LOG=info,bevy_ecs=warn
|
|
// the format used here is super flexible. check out this documentation for more info:
