 With [profiling](/product/profiling/), Sentry allows you to collect and analyze performance profiles from real user devices in production to give you a complete picture of how your application performs in a variety of environments.

 Check out the <PlatformLink to="/performance/">performance setup documentation</PlatformLink> for more detailed information on how to configure sampling. Setting the sample rate to 1.0 means all transactions will be captured. By default, some transactions will be created automatically for common operations like loading a view controller/activity and app startup.

+Rust Profiling alpha is available starting in SDK version `0.29.0`.
+
+</Note>
+
+In order to use Profiling, you first need to enable the `profiling` feature in the `sentry` dependency inside the project `Cargo.toml`:
+
+```cargo
+[dependencies]
+sentry = { version = "0.29.0", features = ["profiling"] }
+```
+
+Once you've completed the step above, you can proceed by enabling it in the SDK:
+
+```rust
+sentry::init((
+    "___DSN___",
+    sentry::ClientOptions {
+        traces_sample_rate: 1.0,
+        enable_profiling: true,
+        profiles_sample_rate: 1.0,
+        ..Default::default()
+    },
+));
+```
