Loading collection data...

After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Hi, I am getting an error in Rust : "variable does not need to be mutable [...] src/tests.rs:49:9" for the variable "input_set".
when I try to run "attempt", this means I cannot submit the solution, even if all of the tests are passing. (Rust version 1.15.1)
