Arbitrary types can be used as HashMap keys, as long as they implement the appropriate traits which can usually be auto-derived.

Covers all u64 sized fib numbers

Mandelbrot ASCII, made by chatgpt 3.5

A macro wrapper around println that has working newlines. Please fix this issue properly @dailyrust-devs

Using the num_bigint crate we can generate much larger numbers with full accuracy.

A Fibonacci sequence iterator that can efficiently generate each number in a single operation each next() call.

Using the dark arts of unsafe rust, we can cast immutable references to mutable pointers, and bypass the need for any slow "safe" Sync objects such as mutexes.

This calculates any arbitrary Fibonacci sequence number in O(1) time, without loops or recursion. Uses the absolute formula to give a best estimate result. Needs an infinite precision math library to give more accurate results.

Even numbers

Prints the current time in a metric time format (100,000 seconds per day)
