Statically constructs new span metadata.
/// For example:
use tracing_core::metadata::{Kind, Level, Metadata};
static FOO_CALLSITE: MyCallsite = MyCallsite {
// ...
};
static FOO_METADATA: Metadata = metadata!{
name: "foo",
target: module_path!(),
level: Level::DEBUG,
fields: &["bar", "baz"],
callsite: &FOO_CALLSITE,
kind: Kind::SPAN,
