Function search_same

Source 
pub fn search_same<T, Hash, Eq>(exprs: &[T], hash: Hash, eq: Eq) -> Vec<Vec<&T>>
where
    Hash: FnMut(&T) -> u64,
    Eq: FnMut(&T, &T) -> bool,
Expand description

Returns a list of groups where elements in each group are equal according to eq

  • Within each group the elements are sorted by the order they appear in exprs
  • The groups themselves are sorted by their first element’s appearence in exprs

Given functions eq and hash such that eq(a, b) == true implies hash(a) == hash(b)
