| ## Including a runtime SDK | ||
|
|
||
| This example covers the integration of the Rust SDK for Wasmtime. First install | ||
| the cargo dependency for the SDK: | ||
| Each language includes some examples demonstrating use with different adapters. You can view these examples here: | ||
|
|
||
| ```toml | ||
| [dependencies] | ||
| dylibso-observe-sdk = { git = "https://github.com/dylibso/observe-sdk.git" } | ||
| ``` | ||
|
|
||
| > **Note**: A runnable example can be found | ||
| > [here](rust/examples/otel-stdout.rs). | ||
| ```rust | ||
| use dylibso_observe_sdk::adapter::otelstdout::OtelStdoutAdapter; | ||
|
|
||
| #[tokio::main] | ||
| pub async fn main() -> anyhow::Result<()> { | ||
| let args: Vec<_> = std::env::args().skip(1).collect(); | ||
| let data = std::fs::read(&args[0])?; | ||
| let function_name = "_start"; | ||
| let config = wasmtime::Config::new(); | ||
|
|
||
| // Create instance | ||
| let engine = wasmtime::Engine::new(&config)?; | ||
| let module = wasmtime::Module::new(&engine, &data)?; | ||
|
|
||
| let adapter = OtelStdoutAdapter::create(); | ||
|
|
||
| // Setup WASI | ||
| let wasi_ctx = wasmtime_wasi::WasiCtxBuilder::new() | ||
| .inherit_env()? | ||
| .inherit_stdio() | ||
| .args(&args.clone())? | ||
| .build(); | ||
|
|
||
| let mut store = wasmtime::Store::new(&engine, wasi_ctx); | ||
| let mut linker = wasmtime::Linker::new(&engine); | ||
| wasmtime_wasi::add_to_linker(&mut linker, |wasi| wasi)?; | ||
|
|
||
| // Provide the observability functions to the `Linker` to be made available | ||
| // to the instrumented guest code. These are safe to add and are a no-op | ||
| // if guest code is uninstrumented. | ||
| let trace_ctx = adapter.start(&mut linker, &data)?; | ||
|
|
||
| let instance = linker.instantiate(&mut store, &module)?; | ||
|
|
||
| // get the function and run it, the events pop into the queue | ||
| // as the function is running | ||
|
|
||
| let f = instance | ||
| .get_func(&mut store, function_name) | ||
| .expect("function exists"); | ||
|
|
||
| f.call(&mut store, &[], &mut []).unwrap(); | ||
|
|
||
| trace_ctx.shutdown().await; | ||
|
|

| Ok(()) | ||
