Enum DefinitionCatalogError 

#[non_exhaustive]
pub enum DefinitionCatalogError {
    InvalidArgument,
    PermissionDenied,
    NotFound,
    FailedPrecondition,
    DigestConflict,
    PreconditionFailed,
    OperationConflict,
}

业务作用：封闭 Definition Catalog 可由协议层安全公开的确定性拒绝类别。

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.

InvalidArgument

请求字段不满足 Catalog 的封闭格式或范围合同。

PermissionDenied

认证主体不是目标 definition 或 capability 的持有者。

NotFound

目标 definition 不存在。

FailedPrecondition

生命周期、集群确认或 capability 等业务前置条件尚未成立。

DigestConflict

相同 tenant/workflow/version 已绑定另一份不可变摘要。

PreconditionFailed

调用方预期的 definition seal 已不再是当前持久事实。

OperationConflict

相同操作身份已绑定另一组动作参数。

Implementations

impl DefinitionCatalogError

pub fn from_error(error: &Error) -> Option<Self>

业务作用：从持久事务上下文包裹的错误链提取 Catalog 确定性拒绝。

参数说明：error 是 Catalog 写入口返回的完整错误链。

返回：命中封闭拒绝时返回对应类别；其它失败返回 None。

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
