Enum SignatureError 

pub enum SignatureError {
    Invalid,
    Unverifiable,
    Expired,
}

Raised to indicate errors when verifying a signature.

Variants

Invalid

Raised if the signature is structurally invalid.

Unverifiable

Raised if the signature is structurally valid but cannot be verified.

Expired

Raised if the signature timestamp cannot be verified.

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<SignatureError> for UnpackError

fn from(value: SignatureError) -> Self

Converts to this type from the input type.

impl PartialEq for SignatureError

fn eq(&self, other: &SignatureError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
