Enum OverwriteExpectation 

#[non_exhaustive]
pub enum OverwriteExpectation {
    Bytes(Vec<u8>),
}

What a snapshotted overwrite must still find at the target before it writes — the compare-and-swap expectation overwrite_checked enforces.

The trash path already holds the prior bytes (it had to copy them to the trash), so the expectation compares bytes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Bytes(Vec<u8>)

The exact prior bytes, from the trash snapshot.
