Enum Error 

#[non_exhaustive]
pub enum Error {
    Encoding(EncodingError),
    Key(KeyError),
    SecretOutOfRange,
    PreSignatureOutOfRange,
    InvalidPreSignaturePoint,
    SignatureMismatch,

}

An adaptor-signature error.

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.

Encoding(EncodingError)

Malformed hex or length.

Key(KeyError)

An invalid key or signature.

SecretOutOfRange

The adaptor secret is zero or not below the curve order.

PreSignatureOutOfRange

The pre-signature’s s' is zero or not below the curve order.

InvalidPreSignaturePoint

The pre-signature’s R is not a valid compressed point.

SignatureMismatch

The signature’s r is not the pre-signature’s.

ExtractFailed

Neither sign of s'·s⁻¹ is the discrete log of the adaptor point.

NoRecoveryId

Neither recovery bit recovers the public key.

NonceGenerationFailed

The RNG failed (try_fill_bytes returned an error) or kept producing unusable nonces (it is broken).

InvalidPreSignature

pre_verify failed: the pre-signature is malformed, or does not complete to a signature by this key on this digest for this adaptor point.

WrongAdaptorSecret

The adaptor secret is not the discrete log of the pre-signature’s adaptor point.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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
