Errors

Variants

NotInitialized

Not initialized

AlreadyInitialized

DriveError

Drive error

Fields

error: String

GroveDBError

GroveDB error, often for issues with proofs

Fields

proof_bytes: Vec<u8>

path_query: Option<PathQuery>

height: u64

time_ms: u64

error: String

ProtocolError

Dash Protocol error

Fields

error: String

EmptyResponseMetadata

Empty response metadata

EmptyVersion

Empty version

NoProofInResult

No proof in response

UnsupportedGroveDBProofVersion

GroveDB proof envelope older than Drive’s MINIMUM_GROVEDB_PROOF_ENVELOPE_VERSION; the payload is refused before Drive verifies it.

Fields

proof: &'static str

Which proof was being read: “proof”, “predecessor proof”, “forward proof”

version: u32

minimum: u32

NotFound

Requested object not found

RequestError

Decode protobuf error

Fields

error: String

ResponseDecodeError

Decode protobuf response error

Fields

error: String

ResultEncodingError

Error when preparing result

Fields

error: String

SignDigestFailed

Cannot generate signature digest for data

Fields

error: String

SignatureVerificationError

Error during signature verification

Fields

error: String

InvalidSignatureFormat

Signature format is invalid

Fields

error: String

InvalidPublicKey

Public key is invalid

Fields

error: String

InvalidSignature

Invalid signature

Fields

error: String

UnexpectedCallbackError

Callback error

Fields

error: String

reason: String

ProofProtocolVersionMismatch

A document query answer names a protocol version other than the one it is verified with. Document queries are rebuilt with the verifier’s protocol version, so the answer is not verified.

Fields

signed: u32

Protocol version in the response metadata

verifier: u32

Protocol version of the verifier’s rules

InvalidVersion(PlatformVersionError)

Invalid version of object in response

ContextProviderNotSet

Context provider is not set

ContextProviderError(ContextProviderError)

Context provider error

QuorumKeyUnavailable

The context provider could not supply the public key of the quorum that signed the proof. The quorum fields come from the response, which is not verified yet; they say which key to look for, not that the quorum exists.

Fields

quorum_type: u32

Quorum type named by the proof

quorum_hash: [u8; 32]

Quorum hash named by the proof

core_chain_locked_height: u32

Core chain locked height from the response metadata

error: ContextProviderError

Why the provider could not supply the key

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

Returns 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<ContextProviderError> for Error

fn from(source: ContextProviderError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<PlatformVersionError> for Error

fn from(source: PlatformVersionError) -> Self

Converts to this type from the input type.

impl From<ProtocolError> for Error

fn from(error: ProtocolError) -> Self

Converts to this type from the input type.
