Enum KeyError 

#[non_exhaustive]
pub enum KeyError {
    InvalidKey(String),
    InvalidSignature,
    UnknownKeyId(String),
    BadSignature(String),
    KeyMismatch(String),
}

Keyring / verification errors.

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.

InvalidKey(String)

Public key bytes malformed.

InvalidSignature

Signature bytes malformed.

UnknownKeyId(String)

No key with this id.

BadSignature(String)

Signature did not verify.

KeyMismatch(String)

Two distinct public keys derived the same key id.

Trait Implementations

impl Debug for KeyError

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

Formats the value using the given formatter.

impl Display for KeyError

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

Formats the value using the given formatter.

impl Error for KeyError

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<KeyError> for ReceiptError

fn from(source: KeyError) -> Self

Converts to this type from the input type.
