Enum TestkitError 

#[non_exhaustive]
pub enum TestkitError {
    Io(Error),
    ReplayExhausted {
        requested: usize,
    },
    ReplayNoMatch {
        left: usize,
    },
    Inner(ProviderError),
}

lc-testkit 统一错误。

通过 [From<TestkitError> for ProviderError] 桥接,让录播/回放 provider 可以直接喂给 chains 等要求 L::Error: Into<ProviderError> 的泛型入口。

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.

Io(Error)

录制/回放过程中的 IO 错误(读文件、写文件等)。

ReplayExhausted

回放队列耗尽:请求条数超过录制条数。

Fields

requested: usize

ReplayNoMatch

ReplayStrategy::Exact 下请求消息签名在录播中无匹配(显式报错,不做 静默 FIFO 兜底);left 为队列剩余条数,便于排查录播与请求的字段漂移。

Fields

left: usize

Inner(ProviderError)

内层模型错误,无损透传真实 provider 错误。

Trait Implementations

impl Debug for TestkitError

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

Formats the value using the given formatter.

impl Display for TestkitError

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

Formats the value using the given formatter.

impl Error for TestkitError

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<Error> for TestkitError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ProviderError> for TestkitError

fn from(source: ProviderError) -> Self

Converts to this type from the input type.

impl From<TestkitError> for ProviderError

fn from(e: TestkitError) -> Self

Converts to this type from the input type.
