Use assert_eq! in copy_from_slice This will print both lengths when the assertion fails instead of just saying that they're different. Output of current stable and nightly (modulo the exact line number): ``` thread 'main' panicked at 'destination and source slices have different lengths', libcore/slice/mod.rs:1645:9 ``` Output after this PR: ``` thread 'main' panicked at 'assertion failed: `(left == right)` left: `123`, right: `456`: destination and source slices have different lengths', libcore/slice/mod.rs:1645:9 ``` Note that I have not run the tests locally.
