Enum SagaResultProcessingError 

#[non_exhaustive]
pub enum SagaResultProcessingError {
    Paused,
    ProducerUnauthorized,
    IdentityInvalid,
    ContractInvalid,
}

业务作用：用封闭类型标记 Saga result 的可信投递分类。

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.

Paused

实例处于 PAUSED，恢复后必须继续处理同一结果。

ProducerUnauthorized

transport 认证出的 producer 无权为目标步骤作证。

IdentityInvalid

envelope 自报身份、派生身份或编码不合法。

ContractInvalid

envelope 与固定实例和 definition 合同不一致。

Implementations

impl SagaResultProcessingError

pub const fn dead_letter_reason(self) -> Option<&'static str>

业务作用：返回可进入 DLT 的稳定 result 原因码。

参数说明: 无。

返回：暂停态返回 None；确定性协议错误返回脱敏原因码。

impl Eq for SagaResultProcessingError

impl Error for SagaResultProcessingError

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.
