业务作用：对进程级 datasource 模式变化给出稳定拒绝原因。

Variants

StandaloneDriverConflict

另一 driver 已占用 standalone 模式。

ManagedModeConflict

受管或引导模式拒绝普通 standalone 注册。

DeferredOnlyDefault

延后引导只允许 default。

DeferredDriverConflict

延后引导已记录另一 driver。

RegistryOccupied

当前模式不能开始新的 Application 引导。

OwnerMismatch

owner token 不属于当前启动。

CatalogOwnerMismatch

catalog 与 typed registry 没有使用同一 owner。

CatalogIdentityMismatch

catalog 实例与已发布实例不同。

DeferredDriverMissing

延后引导没有安装对应 driver 的 default。

DeferredResourcesRemain

清理前仍有延后 standalone 资源。

PublicAdoptDuringBootstrap

无 token 的公开 adopt 不能越过 Bootstrapping。

OrphanedDeferredResources

模式已失去 owner，但仍记录待清理资源。

InvalidDeferredCatalog

catalog 不符合延后 default 的单 driver 合同。

impl Eq for RegistryCoordinationError

impl Error for RegistryCoordinationError

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.
