Available on crate feature e2e-encryption only.

Error type describing different errors that happen when we check or create signatures for a Matrix JSON object.

Variants

UnsupportedAlgorithm

The signature was made using an unsupported algorithm.

InvalidKeyId(Error)

The ID of the signing key isn’t a valid key ID.

MissingSigningKey

The signing key that should create or check a signature is missing.

UserIdMismatch

The user id of signing key differs from the user id that provided the signature.

NotAnObject

The provided JSON value that was signed and the signature should be checked isn’t a valid JSON object.

NoSignatureFound

The provided JSON value that was signed and the signature should be checked isn’t a valid JSON object.

VerificationError(SignatureError)

The signature couldn’t be verified.

InvalidKey(KeyError)

The public key isn’t a valid ed25519 key.

InvalidSignature

The signature could not be decoded.

SigningKeyChanged(Option<Box<Ed25519PublicKey>>, Option<Box<Ed25519PublicKey>>)

The signing key that used to sign the object has been changed.

JsonError(CanonicalJsonError)

The signed object couldn’t be deserialized.

StoreError(CryptoStoreError)

The store ran into an error.

Trait Implementations

impl Debug for SignatureError

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

Formats the value using the given formatter.

impl Display for SignatureError

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

Formats the value using the given formatter.

impl Error for SignatureError

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.
