# wasmprof A library that allows to profile code running inside of wasmtime ## How to use it ```rust // First you want to create a `ProfilerBuilder` like so: // Here we are assuming that you have a `Wasmtime::Store` to pass to the builder. let builder = ProfilerBuilder::new(&mut store); // Then you can set the frequency at which it's going to sample and the kind of weight to use: // Here we are setting the frequency to 1000 (sampling 1000 in a second) and we chose `Fuel` as the weight let builder = builder .frequency(1000) .weight_unit(wasmprof::WeightUnit::Fuel); // finally we can start profiling builder.profile(|store| { // here you would invoke some wasm function though wasmtime, something like this: let func = instance .get_typed_func::(store.as_context_mut(), "fib") .unwrap(); func.call(store.as_context_mut(), 40).unwrap() }) ``` A [complete example](https://github.com/Shopify/wasmprof/blob/main/examples/basic.rs) can be found in the examples folder.
