Enum SignatureError 

pub enum SignatureError {
    Signing,
    Verification,
    InvalidSignature,
}

Defines the errors that can occur during signing and verification.

定义了在签名和验证过程中可能发生的错误。

Variants

Signing

Failed to create a digital signature.

创建数字签名失败。

Verification

Signature verification failed, indicating that the signature is invalid, the data has been tampered with, or the wrong key was used.

签名验证失败，表明签名无效、数据被篡改或使用了错误的密钥。

InvalidSignature

The provided signature is malformed or has an invalid length.

提供的签名格式错误或长度无效。

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<SignatureError> for Error

fn from(source: SignatureError) -> Self

Converts to this type from the input type.

impl PartialEq for SignatureError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
