Errors from crate::sign - commit / operation signing + verification.

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.

NoSignature

Object carries no signature field; verification requires one.

WrongAlgorithm

Signature field uses an algorithm this implementation doesn’t support.

Fields

got: String

Algorithm tag found on the object.

MalformedKey

Public key is not the expected 32 bytes or fails Ed25519 decode.

MalformedSignature

Signature bytes are not the expected 64 bytes.

InvalidSignature

Ed25519 verify rejected the signature.

Encoding(String)

Re-canonicalising the object for verification failed.

RevokedKey

The signing key is present in the revocation list and the object’s timestamp is strictly after the revocation (SPEC §9.2).

Fields

revoked_at: u64

Microseconds-since-epoch moment the key was revoked.

time: u64

The signed object’s time.

Trait Implementations

impl Debug for SignError

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

Formats the value using the given formatter.

impl Display for SignError

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

Formats the value using the given formatter.

impl Error for SignError

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<SignError> for Error

fn from(source: SignError) -> Self

Converts to this type from the input type.
