Enum VerifyResult 

#[non_exhaustive]
pub enum VerifyResult {
    Ok,
    Mismatch {
        stored: String,
        computed: String,
    },
    NoHash,
}

Outcome of checking a dataset against its stored provenance hash.

Returned by Dataset::verify_provenance. NoHash is kept distinct from Mismatch so a dataset that was simply never written with provenance is not reported as corrupt. Non-exhaustive: a future check can report an outcome that is neither a match, a mismatch, nor a missing hash, so match with a _ arm.

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.

Ok

The recomputed hash matches the stored _provenance_sha256 attribute.

Mismatch

The recomputed hash differs from the stored one. Carries both digests (lowercase hex) for diagnostics.

Fields

stored: String

The hash recorded in the _provenance_sha256 attribute.

computed: String

The hash recomputed from the dataset’s current raw bytes.

NoHash

The dataset carries no _provenance_sha256 attribute, so there is nothing to verify against.
