Enum Error 

#[non_exhaustive]
pub enum Error {
    Encoding(EncodingError),
    Key(KeyError),
    InvalidAddress,
    InvalidChecksum,
    InvalidUint,
    InvalidRecoveryValue(u64),
    SignatureOutOfRange,
    MalleableSignature,
    InvalidSignature,
    UnknownStatus(u8),
}

An EVM encoding or 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 scalar.

InvalidAddress

Not 0x followed by 40 hex digits.

InvalidChecksum

A mixed-case address whose EIP-55 checksum is wrong.

InvalidUint

A decimal string that is not a 256-bit unsigned integer.

InvalidRecoveryValue(u64)

v / yParity is not 0, 1, 27 or 28.

SignatureOutOfRange

s is zero or not below the curve order.

MalleableSignature

High s or v not in {27, 28}: the contract reverts with MalleableSignature.

InvalidSignature

The signature does not recover to a key (ecrecover would return the zero address).

UnknownStatus(u8)

An escrow status outside 0, 1, 2.

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

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<EncodingError> for Error

fn from(source: EncodingError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<KeyError> for Error

fn from(source: KeyError) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
