1/// The standard logging macro.
2///
3/// This macro will generically log with the specified `Level` and `format!`
4/// based argument list.
5///
6/// # Examples
7///
8/// ```no_run
9/// use wasmcloud_component::log;
10/// use wasmcloud_component::wasi::logging::logging::Level;
11///
12/// # fn main() {
13/// let data = (42, "Forty-two");
14/// let private_data = "private";
15///
16/// log!(Level::Error, "Received errors: {}, {}", data.0, data.1);
17/// log!(context: "app_events", Level::Warn, "App warning: {}, {}, {}",
18///     data.0, data.1, private_data);
19/// # }
20/// ```
