### Rust WASM Transformer Implementation

Source: https://www.replibyte.com/docs/advanced-guides/web-assembly-transformer

This Rust code reads a string from stdin, reverses it, and prints the result to stdout. It serves as the core logic for the WASM transformer.

```rust
// This is actually the source of the `.wasm` file in this example. Feel free to edit it !  
fn main() {  
    // Read input value from stdin  
    let mut input = String::new();  
    std::io::stdin().read_line(&mut input).unwrap();  
      
    // Transform the value as you see fit (in this case we just reverse the string)  
    let output: String = input.chars().rev().collect();  
      
    // Write transformed value to stdout (simply print)  
    println!("{}", output);
}

```
