 # Quote of the Week
 
-Sadly there was no quote nominated for this week.
+> What I actually value on a daily basis in \[rust is\]
+> I can call code written by other people without unpleasant surprises.
+>
+> ```
+> async fn verify_signature(token: &Jwt) -> Result<Claims, VerificationError>
+> ```
+>
+> Looking at a code snippet:
+> 
+> * I know my JWT token won't be mutated, just accessed ( `&` );
+> * I know the function will probably perform some kind of I/O ( `async` );
+> * I know that the function might fail ( `Result` );
+> * I know its failure modes ( `VerificationError` ).
