Enum SigningError 

pub enum SigningError {
    Key(KeyError),
    Signature(Error),
    Other(Box<dyn Error + Send + Sync>),
}

Errors that occur specifically during a digital signature operation.

Variants

Key(KeyError)

The key required for signing could not be obtained or is invalid.

Signature(Error)

The underlying cryptographic library failed to produce a signature.

Other(Box<dyn Error + Send + Sync>)

An unknown error occurred.

Trait Implementations

impl Debug for SigningError

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

Formats the value using the given formatter.

impl Display for SigningError

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

Formats the value using the given formatter.

impl Error for SigningError

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.
