Programmer's Note

• writer.rs
  • write .wav file headers
  • get file size from metadata
• stores/waveform.rs
  • generate waveform for .wav given frequency and frame count
• parsers/capture.rs
  • use Rc<T> to avoid duplicate data stored in heap
• parsers/input.rs
  • use Peekable<T> for token lookaheads
• parsers/note.rs
  • convert pitch in scientific notation to its frequency in O(1) time
  • use HashMap<K,V> to cache the frequencies
• parsers/repeat.rs
  • use Rc<RefCell<T>> to avoid duplicates and allow mutable references
  • use BTreeMap<K,V> for ordered map
  • higher order functions
