        alg: String,
    },

}

Errors from signing and signature verification.

Variants

Missing

The event carries no signature where one was required.

Fields

event_id: String

Event id of the offending event.

UnpermittedAlgorithm

The signature declares an algorithm this verifier does not permit.

Fields

alg: String

The offending algorithm name.

UnknownKey

No trusted public key matches the signature’s key_id.

Fields

key_id: String

The unknown key id.

Malformed(String)

A key or signature value could not be parsed.

Invalid

A signature was present but did not verify (content, position, or the signature itself was altered).

Fields

event_id: String

Event id of the offending event.

Chain(ChainError)

Canonicalization failed.

Trait Implementations

impl Debug for SignatureError

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

Formats the value using the given formatter.

impl Display for SignatureError

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

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.

impl From<ChainError> for SignatureError

fn from(source: ChainError) -> Self

Converts to this type from the input type.
