Enum EcdsaError 

pub enum EcdsaError {
    Der(DerError),
    InvalidOutputLength,
    Negative,
    IntegerTooLarge,
}

Errors returned while converting ECDSA signatures to or from DER.

Variants

Der(DerError)

The DER input was malformed.

InvalidOutputLength

The output buffer length was zero or not a multiple of two.

Negative

An INTEGER encoded a negative value.

IntegerTooLarge

An INTEGER did not fit in the fixed-width output.

Trait Implementations

impl Clone for EcdsaError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for EcdsaError

impl Debug for EcdsaError

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

Formats the value using the given formatter.

impl Display for EcdsaError

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

Formats the value using the given formatter.

impl Eq for EcdsaError

impl Error for EcdsaError

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<DerError> for EcdsaError

fn from(err: DerError) -> Self

Converts to this type from the input type.

impl PartialEq for EcdsaError

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

Equality operator ==.

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

Inequality operator !=.
