\begin{itemize}

\item Using \textbf{patterns} in conjunction with match expressions and other constructs gives you more control over a program’s control flow.

\item Some example patterns include \mintinline{rust}|x|, \mintinline{rust}|(a, 3)|, and \mintinline{rust}|Some(Color::Red)|. In the contexts in which patterns are valid, these components describe the shape of data.

\begin{itemize}

\item The patterns in this match expression are the None and Some(i) on the left of each arrow.

\item One requirement for match expressions is that they need to be exhaustive in the sense that all possibilities for the value in the match expression must be accounted for.
