interesting things

  • can use if traditionally, or as a conditional in another statemtent
  • continue keyword is a companion to break
  • you can iterate through 1..5 or lists: [1,2,3] with for
  • match is a simplified switch/case statement
  • loop keyword just loops forever
  • let keyword sorts out datatypes later.
  • last line of functions is the return if you omit the semicolon – return can still be used
  • “unit type” is an empty tuple
  • mutable references and exclusive references

built in functions / macros I’ve discovered dbg! println! assert! assert_eq! assert_ne! debug_assert! mut todo! format! unreachable! eprintln!
