}

A bad signature.

Represents the result of an unsuccessful signature verification. It contains all the context that could be gathered until the verification process failed.

VerificationError is used in VerificationResult. See also GoodChecksum.

You can either explicitly match on the variants, or convert to Error using From.

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.

MissingKey

Missing Key

Fields

sig: &'a Signature

The signature.

UnboundKey

Unbound key.

There is no valid binding signature at the time the signature was created under the given policy.

Fields

sig: &'a Signature

The signature.

cert: &'a Cert

The certificate that made the signature.

error: Error

The reason why the key is not bound.

BadKey

Bad key (have a key, but it is not alive, etc.)

Fields

sig: &'a Signature

The signature.

ka: ValidKeyAmalgamation<'a, PublicParts, UnspecifiedRole, bool>

The signing key that made the signature.

error: Error

The reason why the key is bad.

BadSignature

Bad signature (have a valid key, but the signature didn’t check out)

Fields

sig: &'a Signature

The signature.

ka: ValidKeyAmalgamation<'a, PublicParts, UnspecifiedRole, bool>

The signing key that made the signature.

error: Error

The reason why the signature is bad.

MalformedSignature

Malformed signature (no signature creation subpacket, etc.).

Fields

sig: &'a Signature

The signature.

error: Error

The reason why the signature is malformed.

UnknownSignature

A signature that failed to parse at all.

Fields

sig: &'a Unknown

The signature parsed into an crate::packet::Unknown packet.

Trait Implementations

impl<'a> Debug for VerificationError<'a>

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

Formats the value using the given formatter.

impl<'a> Display for VerificationError<'a>

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

Formats the value using the given formatter.

impl<'a> Error for VerificationError<'a>

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<'a> From<VerificationError<'a>> for Error

fn from(e: VerificationError<'a>) -> Error

Converts to this type from the input type.
