I want to try out mphf, but I don't understand how it handles collisions. Are collisions for never seen keys can happen? Maybe add this info to the mphf docs somewhere.

entropy-map/src/map_with_dict.rs

Lines 114 to 120 in 0943c6d

if self.keys.get_unchecked(idx) == key {
// SAFETY: `idx` and `value_idx` are always within bounds (ensure during construction)
let value_idx = *self.values_index.get_unchecked(idx);
Some(self.values_dict.get_unchecked(value_idx))
} else {
None
}

What is this keys check for?
