Enum risc0_zkvm::guest::env::VerifyIntegrityError

#[non_exhaustive]
pub enum VerifyIntegrityError {
    NonEmptyAssumptionsList,
    PrunedValueError(PrunedValueError),
}

Error encountered during a call to verify_integrity.

Note that an error is only returned for “provable” errors. In particular, if the host fails to find a receipt matching the requested claim digest, this is not a provable error. In this case, verify_integrity will not return.

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.

NonEmptyAssumptionsList

Provided crate::ReceiptClaim struct contained a non-empty assumptions list.

This is a semantic error as only unconditional receipts can be verified inside the guest. If there is a conditional receipt to verify, it’s assumptions must first be verified to make the receipt unconditional.

PrunedValueError(PrunedValueError)

Metadata output was pruned and not equal to the zero hash. It is impossible to determine whether the assumptions list is empty.

Trait Implementations

impl Debug for VerifyIntegrityError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for VerifyIntegrityError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for VerifyIntegrityError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<PrunedValueError> for VerifyIntegrityError

fn from(err: PrunedValueError) -> Self

Converts to this type from the input type.
