Enum SignatureError 

pub enum SignatureError {
    BadLength(usize),
    BadRecoveryId(u8),
    Ecdsa(Error),
}

Errors produced when constructing a RecoverableSignature.

Variants

BadLength(usize)

The signature byte slice was not exactly 65 bytes (r || s || v).

BadRecoveryId(u8)

The recovery id byte was not 0 or 1 (after normalising 27/28).

Ecdsa(Error)

The underlying ECDSA library rejected the signature scalars.

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<Error> for SignatureError

fn from(source: Error) -> Self

Converts to this type from the input type.
