You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: table_copy.rs
    path of file: ./repos/wasmi/crates/wasmi/src/engine/translator/tests/op/table
    
    the code of the file until where you have to start completion: use super::*;
use cra
    
fn copy_to_exact() {
    fn test_for(dst: u32, len: u32) {
        test_copy_to_exact(ValueType::FuncRef, dst, len);
        test_copy_to_exact(ValueType::ExternRef, dst, len);
    }
    let values = [u32::from(u16::MAX) + 1, u32::MAX - 1, u32::MAX];
    for dst in values {
        for src in values {
            if dst == src {
                // We skip here because equal `dst` and `src` would
                // allocate just a single function local constant value
                // which our testcase is not prepared for.
                // Ideally we'd have yet another test for that case.
                continue;
            }
            test_for(dst, src);
        }
    }
}
