Enum SignatureError 

#[non_exhaustive]
pub enum SignatureError {
    BadLength(usize),
    BadRecoveryId(u8),
    Hex(FromHexError),
    Ecdsa(Error),
}

Errors produced when constructing a RecoverableSignature.

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.

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).

Hex(FromHexError)

Hexadecimal signature decoding failed.

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.

impl From<FromHexError> for SignatureError

fn from(source: FromHexError) -> Self

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.

Size: 24 bytes

Size for each variant:

• BadLength: 15 bytes
• BadRecoveryId: 1 byte
• Hex: 23 bytes
• Ecdsa: 23 bytes
