## Example

Say “Hello World!” to the w3bstream with rust-sdk.

Make sure you added the ws-sdk crate on Cargo.toml:

```sh
cargo add ws-sdk
```
Then, on your lib.rs:

```rust
use ws_sdk::log::log_info;

#[no_mangle]
pub extern "C" fn start(_: i32) -> i32 {
    log_info("hello world!");
    return 0;
}
```
