# Objective - [`nonstandard_macro_braces`](https://rust-lang.github.io/rust-clippy/master/index.html#nonstandard_macro_braces) is a Clippy lint that enforces what braces certain known macros are allowed to use. - For instance, requiring `println!()` instead of `println!{}`. - I started working on this after seeing https://github.com/TheBevyFlock/bevy_cli/issues/277. ## Solution - Enable `nonstandard_macro_braces` in the workspace. - Configure Clippy so it enforces `[]` braces for `children!`. ## Testing 1. Create `examples/clippy_test.rs`. 2. Paste the following code: ```rust //! Some docs woooooooo use bevy::prelude::*; fn main() { let _ = children!(Name::new("Foo")); } ``` 3. Run `cargo clippy --example clippy_test`. 4. Ensure the following warning is emitted: ```sh warning: use of irregular braces for `children!` macro --> examples/clippy_test.rs:6:13 | 6 | let _ = children!(Name::new("Foo")); | ^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: consider writing: `children![Name::new("Foo")]` | = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#nonstandard_macro_braces = note: requested on the command line with `-W clippy::nonstandard-macro-braces` warning: `bevy` (example "clippy_test") generated 1 warning (run `cargo clippy --fix --example "clippy_test"` to apply 1 suggestion) ``` |

Bevy Benchmarks
This is a crate with a collection of benchmarks for Bevy.
Running benchmarks
Benchmarks can be run through Cargo:
# Run all benchmarks. (This will take a while!)
cargo bench -p benches
# Just compile the benchmarks, do not run them.
cargo bench -p benches --no-run
# Run the benchmarks for a specific crate. (See `Cargo.toml` for a complete list of crates
# tracked.)
cargo bench -p benches --bench ecs
# Filter which benchmarks are run based on the name. This will only run benchmarks whose name
# contains "name_fragment".
cargo bench -p benches -- name_fragment
# List all available benchmarks.
cargo bench -p benches -- --list
# Save a baseline to be compared against later.
cargo bench -p benches --save-baseline before
# Compare the current benchmarks against a baseline to find performance gains and regressions.
cargo bench -p benches --baseline before
Criterion
Bevy's benchmarks use Criterion. If you want to learn more about using Criterion for comparing performance against a baseline or generating detailed reports, you can read the Criterion.rs documentation.
