PDF 文档加密操作特有的错误。

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.

Aes(String)

AES 加密或解密失败。

Rsa(String)

RSA 密钥操作失败。

Signature(String)

RSA 签名创建失败。

Verification(String)

RSA 签名验证失败。

InvalidEncryptedPdf(String)

输入不是本库生成的有效加密 PDF。

InvalidPassword(String)

密码不正确。

InvalidSignedPdf(String)

输入不是有效的签名 PDF 或签名格式错误。

InvalidKey(String)

无法解析私钥。

InvalidCertificate(String)

无法解析证书。

Io(Error)

发生了 I/O 错误。

Trait Implementations

impl Debug for CryptoError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for CryptoError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for CryptoError

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 CryptoError

fn from(source: Error) -> Self

Converts to this type from the input type.
