# Objective Fixes #9625 ## Solution Adds `async-io` as an optional dependency of `bevy_tasks`. When enabled, this causes calls to `futures_lite::future::block_on` to be replaced with calls to `async_io::block_on`. --- ## Changelog - Added a new `async-io` feature to `bevy_tasks`. When enabled, this causes `bevy_tasks` to use `async-io`'s implemention of `block_on` instead of `futures-lite`'s implementation. You should enable this if you use `async-io` in your application.

Cargo Features
Bevy exposes many features to customise the engine. Enabling them add functionalities but often come at the cost of longer compilation times and extra dependencies.
Default Features
The default feature set enables most of the expected features of a game engine, like rendering in both 2D and 3D, asset loading, audio and UI. To help reduce compilation time, consider disabling default features and enabling only those you need.
| feature name | description |
|---|---|
| android_shared_stdcxx | Enable using a shared stdlib for cxx on Android |
| animation | Enable animation support, and glTF animation loading |
| bevy_animation | Provides animation functionality |
| bevy_asset | Provides asset functionality |
| bevy_audio | Provides audio functionality |
| bevy_core_pipeline | Provides cameras and other basic render pipeline features |
| bevy_gilrs | Adds gamepad support |
| bevy_gizmos | Adds support for rendering gizmos |
| bevy_gltf | glTF support |
| bevy_pbr | Adds PBR rendering |
| bevy_render | Provides rendering functionality |
| bevy_scene | Provides scene functionality |
| bevy_sprite | Provides sprite functionality |
| bevy_text | Provides text functionality |
| bevy_ui | A custom ECS-driven UI framework |
| bevy_winit | winit window and input backend |
| default_font | Include a default font, containing only ASCII characters, at the cost of a 20kB binary size increase |
| hdr | HDR image format support |
| ktx2 | KTX2 compressed texture support |
| multi-threaded | Enables multithreaded parallelism in the engine. Disabling it forces all engine tasks to run on a single thread. |
| png | PNG image format support |
| tonemapping_luts | Include tonemapping Look Up Tables KTX2 files |
| vorbis | OGG/VORBIS audio format support |
| webgl2 | Enable some limitations to be able to use WebGL2. If not enabled, it will default to WebGPU in Wasm |
| x11 | X11 display server support |
| zstd | For KTX2 supercompression |
Optional Features
| feature name | description |
|---|---|
| accesskit_unix | Enable AccessKit on Unix backends (currently only works with experimental screen readers and forks.) |
| async-io | Use async-io's implementation of block_on instead of futures-lite's implementation. This is preferred if your application uses async-io. |
| basis-universal | Basis Universal compressed texture support |
| bevy_ci_testing | Enable systems that allow for automated testing on CI |
| bevy_dynamic_plugin | Plugin for dynamic loading (using libloading) |
| bmp | BMP image format support |
| dds | DDS compressed texture support |
| detailed_trace | Enable detailed trace event logging. These trace events are expensive even when off, thus they require compile time opt-in |
| dynamic_linking | Force dynamic linking, which improves iterative compile times |
| exr | EXR image format support |
| filesystem_watcher | Enables watching the filesystem for Bevy Asset hot-reloading |
| flac | FLAC audio format support |
| glam_assert | Enable assertions to check the validity of parameters passed to glam |

| trace_tracy_memory | Tracing support, with memory profiling, exposing a port for Tracy |
| wav | WAV audio format support |
| wayland | Wayland display server support |
| webp | WebP image format support |
| wgpu_trace | Save a trace of all wgpu calls |
| zlib | For KTX2 supercompression |
