 ### Examples
 
 This crate provides an example demonstrating how to serialize and deserialize Sv2 message frames:
 
 1. **[Sv2 Frame](https://github.com/stratum-mining/stratum/blob/main/protocols/v2/framing-sv2/examples/sv2_frame.rs)**:
-   Constructs, serializes, and deserialize a regular Sv2 message frame (`Sv2Frame`).
