Understand it, then run it

Todayrust
// This program demonstrates the concept of nested ActiveModel and cascade operations in SeaORM 2.0.
// The actual SeaORM crate is not available in the standard library, so we only print a placeholder
// message to illustrate what the API would look like once the change ships.
fn main() {
// In a real program you would create nested ActiveModel instances and call `save` or `delete`.
println!("Nested ActiveModel and cascade operations are now supported in SeaORM 2.0.");
}
What it printed when we ran it on Rust 1.98.1 (edition 2024)
Nested ActiveModel and cascade operations are now supported in SeaORM 2.0.
Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
