# Objective - Contributes to #16877 ## Solution - Moved `hashbrown`, `foldhash`, and related types out of `bevy_utils` and into `bevy_platform_support` - Refactored the above to match the layout of these types in `std`. - Updated crates as required. ## Testing - CI --- ## Migration Guide - The following items were moved out of `bevy_utils` and into `bevy_platform_support::hash`: - `FixedState` - `DefaultHasher` - `RandomState` - `FixedHasher` - `Hashed` - `PassHash` - `PassHasher` - `NoOpHash` - The following items were moved out of `bevy_utils` and into `bevy_platform_support::collections`: - `HashMap` - `HashSet` - `bevy_utils::hashbrown` has been removed. Instead, import from `bevy_platform_support::collections` _or_ take a dependency on `hashbrown` directly. - `bevy_utils::Entry` has been removed. Instead, import from `bevy_platform_support::collections::hash_map` or `bevy_platform_support::collections::hash_set` as appropriate. - All of the above equally apply to `bevy::utils` and `bevy::platform_support`. ## Notes - I left `PreHashMap`, `PreHashMapExt`, and `TypeIdMap` in `bevy_utils` as they might be candidates for micro-crating. They can always be moved into `bevy_platform_support` at a later date if desired. |

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.
