Enum TestkitError 

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

Unified lc-testkit error.

Bridges via [From<TestkitError> for ProviderError], so the record/replay provider can be fed directly into generic entry points like chains that require L::Error: Into<ProviderError>.

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)

IO error during recording/replaying (reading/writing files, etc.).

ReplayExhausted

Replay queue exhausted: more requests than recorded exchanges.

Fields

requested: usize

ReplayNoMatch

No recording matches the request message signature under ReplayStrategy::Exact (explicit error, no silent FIFO fallback); left is the remaining queue length, useful for debugging field drift between the recording and the request.

Fields

left: usize

Inner(ProviderError)

Inner model error, passed through losslessly from the real provider error.

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.
