Function wasmtime_wasi::preview2::with_ambient_tokio_runtime

pub fn with_ambient_tokio_runtime<R>(f: impl FnOnce() -> R) -> R

Executes the closure f with an “ambient Tokio runtime” which basically means that if code in f tries to get a runtime Handle it’ll succeed.

If a Handle is already available, e.g. in async contexts, then f is run immediately. Otherwise for synchronous contexts this crate’s fallback runtime is configured and then f is executed.
