FAQ

Question: Very large maps take a long time to compile?

Answer: Rustc is very slow to compile big expressions with many literals (including integers and float literals). Work around this by either using explicitly typed literals, or explicitly typed conversions. See https://github.com/bluss/maplit/issues/14 for more information.
