| This example connects to an echo server on `wss://echo.websocket.org`, |
| sends a `ping` message, and receives the response. |
| |
| ## `Cargo.toml` |
| |
| The `Cargo.toml` enables features necessary to create a `WebSocket` object and |
| to access events such as `MessageEvent` or `ErrorEvent`. |
| |
| ```toml |
| {{#include ../../../examples/websockets/Cargo.toml}} |
| ``` |
| |
| ## `src/lib.rs` |
| |
| This code shows the basic steps required to work with a `WebSocket`. |
| At first it opens the connection, then subscribes to events `onmessage`, `onerror`, `onopen`. |
| After the socket is opened it sends a `ping` message, receives an echoed response |
| and prints it to the browser console. |
| |
| ```rust |
| {{#include ../../../examples/websockets/src/lib.rs}} |
| ``` |
