pub struct AlreadyInitialized;

进程通知实现已经由业务初始化，不允许覆盖正在使用的实现。

Trait Implementations

impl Clone for AlreadyInitialized

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AlreadyInitialized

impl Debug for AlreadyInitialized

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

Formats the value using the given formatter.

impl Display for AlreadyInitialized

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

业务作用：报告重复初始化而不暴露业务实现或渠道配置。

返回：写入稳定错误说明，不包含通知内容。

impl Eq for AlreadyInitialized

impl Error for AlreadyInitialized

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 AlreadyInitialized

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