Errors produced when creating, decoding, or validating an IPNS Record.

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.

RecordTooLarge

The record exceeds the 10 KiB IPNS size limit.

MissingSignature

The record is missing its V2 signature.

EmptyData

The record is missing its data field.

NameMismatch

The signing key does not correspond to the IPNS name.

MissingPublicKey

The IPNS name does not inline a public key and the record omits one.

InvalidSignature

The V2 signature failed verification.

Expired

The record’s EOL validity has elapsed.

DataMismatch

The dag-cbor data does not match the record’s protobuf fields.

InvalidValidityType

Unrecognized validity type.

Protobuf(Error)

Malformed protobuf.

Cbor(Box<dyn Error + Send + Sync + 'static>)

Malformed dag-cbor data.

InvalidValidity(ParseError)

Malformed EOL validity timestamp.

SigningError(SigningError)

A key or signing operation failed.

InvalidPublicKey(DecodingError)

Invalid public key.

Multihash(Error)

Malformed multihash or peer id.

ReservedMetadataKey(String)

A metadata key collides with a reserved IPNS field name.

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, f: &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<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(e: ParseError) -> Self

Converts to this type from the input type.
