# Objective - Many strings in bevy_ecs are created but only used for debug: system name, component name, ... - Those strings make a significant part of the final binary and are no use in a released game ## Solution - Use [`strings`](https://linux.die.net/man/1/strings) to find ... strings in a binary - Try to find where they come from - Many are made from `type_name::<T>()` and only used in error / debug messages - Add a new structure `DebugName` that holds no value if `debug` feature is disabled - Replace `core::any::type_name::<T>()` by `DebugName::type_name::<T>()` ## Testing Measurements were taken without the new feature being enabled by default, to help with commands ### File Size I tried building the `breakout` example with `cargo run --release --example breakout` |`debug` enabled|`debug` disabled| |-|-| |81621776 B|77735728B| |77.84MB|74.13MB| ### Compilation time `hyperfine --min-runs 15 --prepare "cargo clean && sleep 5" 'RUSTC_WRAPPER="" cargo build --release --example breakout' 'RUSTC_WRAPPER="" cargo build --release --example breakout --features debug'` ``` breakout' 'RUSTC_WRAPPER="" cargo build --release --example breakout --features debug' Benchmark 1: RUSTC_WRAPPER="" cargo build --release --example breakout Time (mean ± σ): 84.856 s ± 3.565 s [User: 1093.817 s, System: 32.547 s] Range (min … max): 78.038 s … 89.214 s 15 runs Benchmark 2: RUSTC_WRAPPER="" cargo build --release --example breakout --features debug Time (mean ± σ): 92.303 s ± 2.466 s [User: 1193.443 s, System: 33.803 s] Range (min … max): 90.619 s … 99.684 s 15 runs Summary RUSTC_WRAPPER="" cargo build --release --example breakout ran 1.09 ± 0.05 times faster than RUSTC_WRAPPER="" cargo build --release --example breakout --features debug ```
