Enum FormatError 

pub enum FormatError {
    Serialization(BincodeError),
    InvalidCiphertext,
    InvalidKeyType,
    InvalidKey,
}

Errors related to data formatting, serialization, and structure validation.

与数据格式、序列化和结构验证相关的错误。

Overview | 概述

These errors occur when data doesn’t conform to expected formats or when serialization/deserialization operations fail. They typically indicate either corrupted data or version incompatibilities.

当数据不符合预期格式或序列化/反序列化操作失败时会发生这些错误。 它们通常表示数据损坏或版本不兼容。

Common Causes | 常见原因

• Corrupted or truncated data

• Version mismatches between serialization formats

• Invalid key material or algorithm parameters

• Malformed ciphertext or signature data

• 损坏或截断的数据

• 序列化格式之间的版本不匹配

• 无效的密钥材料或算法参数

• 格式错误的密文或签名数据

Variants

Serialization(BincodeError)

Binary serialization or deserialization failure.

二进制序列化或反序列化失败。

This error occurs when bincode cannot serialize or deserialize data, typically due to:

• Incompatible data structure versions
• Corrupted serialized data
• Insufficient buffer space

当 bincode 无法序列化或反序列化数据时发生此错误，通常由于：

• 不兼容的数据结构版本
• 损坏的序列化数据
• 缓冲区空间不足

Recovery | 恢复

• Verify data integrity

• Check version compatibility

• Ensure sufficient buffer space

• 验证数据完整性

• 检查版本兼容性

• 确保足够的缓冲区空间

InvalidCiphertext

Invalid or corrupted ciphertext format.

无效或损坏的密文格式。

This error indicates that the ciphertext data is malformed, incomplete, or has been corrupted. Common causes include:

• Data truncation during transmission or storage
• Bit flips due to hardware errors
• Incorrect data handling or parsing

此错误表示密文数据格式错误、不完整或已损坏。常见原因包括：

• 传输或存储期间的数据截断
• 硬件错误导致的位翻转
• 不正确的数据处理或解析

Security Implications | 安全影响

This error should be treated as a potential security issue. Never attempt to process malformed ciphertext.

此错误应被视为潜在的安全问题。 永远不要尝试处理格式错误的密文。

InvalidKeyType

Unsupported or invalid key type.

不支持或无效的密钥类型。

This error occurs when:

• A key is used with an incompatible algorithm
• The key type is not supported by the current configuration
• Key metadata is corrupted or missing

在以下情况下发生此错误：

• 密钥与不兼容的算法一起使用
• 当前配置不支持密钥类型
• 密钥元数据损坏或丢失

InvalidKey

Invalid key material or structure.

无效的密钥材料或结构。

This error indicates that the key data itself is invalid:

• Incorrect key length for the algorithm
• Invalid key format or encoding
• Corrupted key material
• Missing required key components

此错误表示密钥数据本身无效：

• 算法的密钥长度不正确
• 无效的密钥格式或编码
• 损坏的密钥材料
• 缺少必需的密钥组件

Security Note | 安全注意

Invalid keys should never be used for cryptographic operations. Always validate key material before use.

无效密钥永远不应用于密码操作。 使用前始终验证密钥材料。

Trait Implementations

impl Debug for FormatError

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

Formats the value using the given formatter.

impl Display for FormatError

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

Formats the value using the given formatter.

impl Error for FormatError

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<BincodeError> for FormatError

fn from(source: BincodeError) -> Self

Converts to this type from the input type.

impl From<FormatError> for Error

fn from(source: FormatError) -> Self
