anewer appends lines from stdin to a file if they don't already exist in the file. You could also use it asuniq withoutsort. This is a rust version oftomnomnom/anew. It makes use oftkaitchuck/aHash to cut down runtime to ~50%. Since only hashed lines are held in memory, it cuts down memory usage for inputs with long lines. Which is similar howhuniq works.
