Function show_notes::e003::demonstrate_match

pub fn demonstrate_match()

Shows in a bit more detail how match works.

Note that the pattern matches include matching against numbers, tuple types, and more. Big takeaways:

• You can match against all sorts of types.
• You have to match exhaustively. Handle "everything else" with _ as the sole component of the match arm.
• You can destructure complex types into their components. You can ignore components of complex types with _ as well.
