Enum ProfilingConfig

Source

pub enum ProfilingConfig {
    None,
    Guest {
        path: PathBuf,
        sample_period: Duration,
    },
    Native(ProfilingStrategy),
}

Expand description

Configuration for profiling Wasm execution.

Viceroy supports two types of profiling:

Guest profiling: Profiles the WebAssembly guest code itself, producing Firefox profiler compatible JSON.
Native profiling: Profiles wasmtime’s JIT compiler for debugging across guest, viceroy and wasmtime.

Variants§

§

None

No profiling enabled

§

Guest

Profile the WebAssembly guest code

Fields

§path: PathBuf

Path to write profiling results. In serve mode, this should be a directory where per-request profiles are written. In run mode, this is a single file.

§sample_period: Duration

Period at which the guest should be sampled (default: 50μs)

§

Native(ProfilingStrategy)

Profile wasmtime’s JIT compiler using native profiling tools
