Enum RuntimeError 

#[non_exhaustive]
pub enum RuntimeError {
    SpawnFailed(Error),
    ThreadPanicked,
    ScenariosFailed(String),
}

Runtime and system errors outside the user’s control.

These represent environmental failures (OS thread limits, thread panics) that cannot be resolved by changing configuration.

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.

SpawnFailed(Error)

The OS refused to spawn a new thread.

Preserves the original std::io::Error via the #[source] attribute so callers can inspect the error kind (e.g., resource exhaustion) programmatically via the standard std::error::Error::source chain.

ThreadPanicked

A scenario thread panicked during execution.

ScenariosFailed(String)

One or more scenarios in a multi-scenario run failed.

The error messages from all failed scenario threads are collected and joined into a single string. This variant exists to prevent thread-level sink, runtime, or generator errors from being misclassified as ConfigError when collected at the multi-runner level.

Trait Implementations

impl Debug for RuntimeError

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

Formats the value using the given formatter.

impl Display for RuntimeError

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

Formats the value using the given formatter.

impl Error for RuntimeError

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<RuntimeError> for SondaError

fn from(source: RuntimeError) -> Self

Converts to this type from the input type.
