WARNING: this crate is for the purpose of demonstration about how terrible a rust dependency could do, please DO NOT ACTUALLY USE IT IN PRODUCTION. It's not in the crates.io, but the crates there could do something even worse.
Rickrolling at compile-time.
For any crate that depends on this, the first 5 seconds of Never gonna give you up by Rick Astley will be played for N+1 times when compiling this crate, where N is the number of macro rickroll_rs::rickroll! used in the crate. The extra 1 time is in the build.rs
