Understand it, then run it

// This program demonstrates the current state of DMA mapping in Rust 1.98.1 (edition 2024).
// The new tooling update that improves resistance to Rust abstractions for DMA mapping
// has not yet shipped, so we simply simulate the mapping with a placeholder message.
fn main() {
    // In a real embedded environment, this would involve unsafe code to map a buffer
    // for DMA. Here we just print a confirmation to show the intended output.
    println!("Buffer mapped for DMA (demo).");
}

What it printed when we ran it on Rust 1.98.1 (edition 2024)

Buffer mapped for DMA (demo).

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.
