Errors surfaced by every public API in this crate.

Variants

NotDidKey(String)

Input was not a did:key:z… string.

InvalidMultibase(String)

Multibase header or body rejected (only base58btc ‘z’ accepted).

UnknownCodec(u64)

Multicodec varint prefix did not match any supported algorithm.

InvalidKeyLength

Key bytes were the wrong length for the declared codec.

Fields

codec: &'static str

expected: usize

actual: usize

MalformedJwt(String)

JWT compact serialisation is malformed (segment count / base64).

InvalidHeader(String)

JWT header rejected — wrong alg, missing key binding, alg does not match the bound did:key, etc.

InvalidClaims(String)

JWT claims rejected — htm/htu/iat mismatch.

BadSignature(String)

Cryptographic signature verification failed.

KeyParse(String)

Failure parsing an underlying elliptic-curve key or signature.

Json(Error)

Serde / JSON decode failures.

Base64(DecodeError)

Base64 decode failures.

Trait Implementations

impl Debug for DidKeyError

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

Formats the value using the given formatter.

impl Display for DidKeyError

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

Formats the value using the given formatter.

impl Error for DidKeyError

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<DecodeError> for DidKeyError

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl From<Error> for DidKeyError

fn from(source: Error) -> Self

Converts to this type from the input type.
