Add the Rerun crate using cargo add rerun.
You'll additionally need to install the Viewer.
Reduce dependencies and compile time
The default features of the rerun crate include a lot more than the logging SDK, such as the gRPC server (server), the dataframe API (dataframe), file importers (importers), and support for video, images, audio, and the map view.
If you only need to log data, turn off the default features and enable only sdk:
[dependencies]
rerun = { version = "…", default-features = false, features = ["sdk"] }Then add back the features you need, for example image for the image crate integration, or glam for math type conversions.
See the list of features.
The native Viewer is not part of the default features.
Only enable native_viewer if you want to embed or extend the Viewer in your own app, since it adds many dependencies.
To show your data, spawn() starts the rerun binary that you installed separately.
Debug builds of Rerun run slowly.
To make them faster, compile your dependencies with optimizations, in your Cargo.toml:
[profile.dev.package."*"]
opt-level = 2Your own code is still built without optimizations, and dependencies are only rebuilt when they change.
