# Objective One of the changes in #14704 made `DynamicFunction` effectively the same as `DynamicClosure<'static>`. This change meant that the de facto function type would likely be `DynamicClosure<'static>` instead of the intended `DynamicFunction`, since the former is much more flexible. We _could_ explore ways of making `DynamicFunction` implement `Copy` using some unsafe code, but it likely wouldn't be worth it. And users would likely still reach for the convenience of `DynamicClosure<'static>` over the copy-ability of `DynamicFunction`. The goal of this PR is to fix this confusion between the two types. ## Solution Firstly, the `DynamicFunction` type was removed. Again, it was no different than `DynamicClosure<'static>` so it wasn't a huge deal to remove. Secondly, `DynamicClosure<'env>` and `DynamicClosureMut<'env>` were renamed to `DynamicFunction<'env>` and `DynamicFunctionMut<'env>`, respectively. Yes, we still ultimately kept the naming of `DynamicFunction`, but changed its behavior to that of `DynamicClosure<'env>`. We need a term to refer to both functions and closures, and "function" was the best option. [Originally](https://discord.com/channels/691052431525675048/1002362493634629796/1274091992162242710), I was going to go with "callable" as the replacement term to encompass both functions and closures (e.g. `DynamciCallable<'env>`). However, it was [suggested](https://discord.com/channels/691052431525675048/1002362493634629796/1274653581777047625) by @SkiFire13 that the simpler "function" term could be used instead. While "callable" is perhaps the better umbrella term—being truly ambiguous over functions and closures— "function" is more familiar, used more often, easier to discover, and is subjectively just "better-sounding". ## Testing Most changes are purely swapping type names or updating documentation, but you can verify everything still works by running the following command: ``` cargo test --package bevy_reflect ``` |
