Use Rust to print a trapezium pattern made of stars (*) and dots (.) based on the input n:
```
fn main() {
let n = 3;
// Print upper half of the trapezium
for i in 0..n {
println!("{}{}{}", "*".repeat(n - 1 - i), ".".repeat(2 * i + 1), "*".repeat(n - 1 - i));
}
// Print lower half of the trapezium
for i in 0..n-1 {
println!("{}{}{}", "*".repeat(i + 1), ".".repeat(2 * (n - 2 - i) + 1), "*".repeat(i + 1));
}
}
```
