bjorn3 fbf08ac545 Faster compilation of bevy_diagnostic (#1235) ... * Remove AHashExt There is little benefit of Hash*::new() over Hash*::default(), but it does require more code that needs to be duplicated for every Hash* in bevy_utils. It may also slightly increase compile times. * Add StableHash* to bevy_utils * Use StableHashMap instead of HashMap + BTreeSet for diagnostics This is a significant reduction in the release mode compile times of bevy_diagnostics ``` Benchmark #1: touch crates/bevy_diagnostic/src/lib.rs && cargo build --release -p bevy_diagnostic -j1 Time (mean ± σ): 3.645 s ± 0.009 s [User: 3.551 s, System: 0.094 s] Range (min … max): 3.632 s … 3.658 s 20 runs ``` ``` Benchmark #1: touch crates/bevy_diagnostic/src/lib.rs && cargo build --release -p bevy_diagnostic -j1 Time (mean ± σ): 2.938 s ± 0.012 s [User: 2.850 s, System: 0.090 s] Range (min … max): 2.919 s … 2.969 s 20 runs ```		2021-01-12 13:21:45 -08:00
