Enum SerializerError 

pub enum SerializerError {
    EncodeFailed(String),
    DecodeFailed(String),
    FormatMismatch {
        expected: &'static str,
        actual: &'static str,
    },
    VersionIncompatible,
}

Serializer error (A2-2: fine-grained variants) | 序列化错误（A2-2：精细错误变体）

• EncodeFailed: serde encode failure — log data model, do not retry 编码失败：记录数据模型问题，不要重试
• DecodeFailed: malformed payload — log and consider fallback/migration 解码失败：记录并考虑降级/迁移
• FormatMismatch: e.g. JsonSerializer sees binary magic — check config 格式不匹配：检查序列化器配置
• VersionIncompatible: reserved for schema evolution 版本不兼容：预留模式演进

Variants

EncodeFailed(String)

Encoding failed | 编码失败

DecodeFailed(String)

Decoding failed | 解码失败

FormatMismatch

Format mismatch between serializer and payload | 序列化器与 payload 格式不匹配

Fields

expected: &'static str

Expected format name | 期望格式名

actual: &'static str

Actual detected format | 实际探测到的格式

VersionIncompatible

Version incompatible (future schema evolution) | 版本不兼容（未来模式演进）

Trait Implementations

impl Clone for SerializerError

fn clone(&self) -> SerializerError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SerializerError

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

Formats the value using the given formatter.

impl Display for SerializerError

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

Formats the value using the given formatter.

impl Eq for SerializerError

impl Error for SerializerError

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 PartialEq for SerializerError

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

Equality operator ==.

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

Inequality operator !=.
