Pattern Reference

Borrow After Move

// BEFORE (ERROR)
let data = vec![1, 2, 3];
let moved = data;
println!("{}", data.len()); // ERROR: borrow after move


// AFTER (FIXED)
let data = vec![1, 2, 3];
let len = data.len(); // Capture before move
let moved = data;
println!("{}", len); // OK: using captured value

Send Trait with Guards

// BEFORE (ERROR)
let guard = lock.write();
do_something(&guard);
await_something().await; // ERROR: guard held across await


// AFTER (FIXED)
{
    let guard = lock.write();
    do_something(&guard);
} // guard dropped here
await_something().await; // OK: no guard held
