Enum SignatureError 

#[non_exhaustive]
pub enum SignatureError {
    InvalidRecovery(u64),
    SOutOfRange,
    ROutOfRange,
    NotCanonical,
    Unrecoverable,
}

Why a claim signature was rejected.

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.

InvalidRecovery(u64)

v is not 0, 1, 27 or 28.

SOutOfRange

s is 0 or at least the curve order.

ROutOfRange

r is 0 or at least the curve order.

NotCanonical

v is not 27/28 or s is high: the contract would reject it (MalleableSignature).

Unrecoverable

No public key recovers from the signature.

Trait Implementations

impl Clone for SignatureError

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 SignatureError

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 Eq for SignatureError

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 EvmError

fn from(source: SignatureError) -> Self

Converts to this type from the input type.

impl PartialEq for SignatureError

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

Equality operator ==.

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

Inequality operator !=.
