# 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 ```

# Functionality
|
|
|
|
## Enables multithreading support. Schedules will attempt to run systems on
|
|
## multiple threads whenever possible.
|
|
multi_threaded = ["bevy_tasks/multi_threaded", "dep:arrayvec"]
|
|
|
|
## Adds serialization support through `serde`.
|
|

|
|
|
|
## Adds runtime reflection support using `bevy_reflect`.
|
|
bevy_reflect = ["dep:bevy_reflect"]
|
|
|
|
## Extends reflection support to functions.
|
|
reflect_functions = ["bevy_reflect", "bevy_reflect/functions"]

|
|
|
## Enables automatic backtrace capturing in BevyError
|
|

|
# Debugging Features
|
|
|
|
## Enables `tracing` integration, allowing spans and other metrics to be reported
|
|
## through that framework.
|
|
trace = ["std", "dep:tracing", "bevy_utils/debug"]
|
|
|
|
## Enables a more detailed set of traces which may be noisy if left on by default.
|
|
detailed_trace = ["trace"]
|
|
|
|
## Provides system stepping support, allowing them to be paused, stepped, and
|
|
## other debug operations which can help with diagnosing certain behaviors.
|
|
bevy_debug_stepping = []
|
|
|
|
## Provides more detailed tracking of the cause of various effects within the ECS.

## This will often provide more detailed error messages.

# Executor Backend
|

|
## This backend is incompatible with `no_std` targets.

async_executor = ["std", "bevy_tasks/async_executor"]

# Platform Compatibility
|
|
|
|
## Allows access to the `std` crate. Enabling this feature will prevent compilation
|
|
## on `no_std` targets, but provides access to certain additional features on
|
|
## supported platforms.
