Struct BridgeError 

pub struct BridgeError {
    pub code: &'static str,
    pub message: String,
}

绑定层（C FFI / wasm / PyO3）对外报错的统一形状。

三条出口都把它落成 {"error": "<message>", "code": "<code>"}：message 面向人，code 面向程序——各语言绑定据此映射到自己的异常类型或哨兵错误， 无需解析文案。

Fields

code: &'static str

机器可读的错误分类： invalid_date（日期非法）、invalid_time_index（时辰越界）、 invalid_argument（其余入参或配置非法）、internal（库内部缺陷）。

message: String

面向人的错误描述，小写起首、以冒号引出细节。

Implementations

impl BridgeError

pub fn invalid_argument(message: impl Into<String>) -> Self

入参或配置非法（invalid_argument）。

pub fn internal(message: impl Into<String>) -> Self

库内部缺陷，含 catch_unwind 兜住的 panic（internal）。

Trait Implementations

impl Clone for BridgeError

fn clone(&self) -> BridgeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BridgeError

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

Formats the value using the given formatter.

impl Display for BridgeError

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

Formats the value using the given formatter.

impl Eq for BridgeError

impl Error for BridgeError

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 From<IztroError> for BridgeError

fn from(e: IztroError) -> Self

Converts to this type from the input type.

impl PartialEq for BridgeError

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

Equality operator ==.

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

Inequality operator !=.
