Type Definition vxdraw::Logger

type Logger = Box<dyn FnMut(u8, Box<dyn Fn(&mut Formatter) -> Result + Send + Sync>)>;

Logger bridge type used when initializing VxDraw

The first argument is the log level, with 0 being severe and 255 being trace. The second argument is the context label. The final argument is an arbitrary formatter that outputs text, this text may be on multiple lines.

In most tests we use the logger from another crate because it has spawn_test, which is useful for quickly debugging a failing test.
