nit: IMO this would read slightly nicer as match, but no hard feelings.
E.g. like (untested):
let snapshot_verified = match source_manifest.verify_state() {
Ok(Some(VerifyState::Ok)) => true,
_ => false,
};

Maybe it might be nicer to use an ignore_snapshot bool shared by this and the
encrypted-only branch and then move the early exit after that to a common if?

could use break after this, the value of snapshot_encrypted won't change after
this anymore.

Alternatively use a more functional style, e.g. something like (untested):
let snapshot_encrypted = source_manifest
.files()
.all(|&file| file.chunk_crypt_mode() == CryptMode::Encrypt);

same as above w.r.t. code style nit.
