Todo

A list of topics that are worth considering. Some of these topics have been taken from the Python 3 Cookbook.

• ** Iterators **
  • Finding the largest or smallest N Items in an Slice, Iterator, or Range(?) object like a Set.
  • Implementing a Priority Queue (Constructing an iterator problem).
  • Implementing a mutable iterator.
  • Intersecting Hasmaps? Union of Hashmaps?
  • Deduplicating items in an iterator.
  • Finding most requently occuring item in slice or general iterator.
  • Doing a "GroupBy" while iterating over product types.
  • Expanding a list, ie: using flat_map, like x.iter().flat_map(|&n| vec![n, n+1, n+2]).collect().
• borrowck issues! D:
  • Borrowed self in if {} else {} clasue SO ref
  • Mutating self after borrowing self. SO ref
  • Using lifetimes to control your borrows. SO ref
  • Good question, what's the morale of the story? SO ref
  • When to clarify when you need iter, into_iter, or iter_mut? SO ref
  • Coerce multiple iterators, and iterator proxy. Ie, why doesn't this work:

    for y in if reverse { (0..4).rev() } else { 0..4 } { ..

• Closures Closures Closures!!
  • Functions that return functions, see this SO ref
  • Get some good examples from this post here
• ** Uncategorized **
  • Caching function return values. Hygiene?

cookbook's Issues

Iterator/Vec examples

• Iterate while appending, imperative
• Iterate while appending, functional
• Remove elements in-place
• Filter
• Borrowck concerns when passing Iterators around
• Accumulator pattern (fold)
• Demonstrate what flat_map means
