Enum ChaosError 

pub enum ChaosError {
    MemoryLimitExceeded {
        limit: usize,
        used: usize,
    },
    Timeout {
        elapsed: Duration,
        limit: Duration,
    },
    SignalInjectionFailed {
        signal: i32,
        reason: String,
    },
}

Error types for chaos engineering scenarios.

Based on renacer’s chaos error taxonomy. These errors represent intentional failure modes injected during chaos testing.

Examples

use certeza::chaos::ChaosError;
use std::time::Duration;

let error = ChaosError::MemoryLimitExceeded {
    limit: 1024,
    used: 2048,
};

assert_eq!(
    format!("{}", error),
    "Memory limit exceeded: 2048 > 1024 bytes"
);

Variants

MemoryLimitExceeded

Memory allocation exceeded configured limit.

Represents out-of-memory conditions under resource constraints.

Fields

limit: usize

Configured memory limit in bytes

used: usize

Actual memory usage in bytes

Timeout

Operation exceeded configured timeout.

Represents deadline violations in time-constrained scenarios.

Fields

elapsed: Duration

Actual elapsed time

limit: Duration

Configured timeout limit

SignalInjectionFailed

Signal injection failed.

Represents failures in interrupt simulation (SIGINT, SIGTERM, etc.).

Fields

signal: i32

Signal number (e.g., 2 for SIGINT, 15 for SIGTERM)

reason: String

Human-readable failure reason

Trait Implementations

impl Clone for ChaosError

fn clone(&self) -> ChaosError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChaosError

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

Formats the value using the given formatter.

impl Display for ChaosError

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

Formats the value using the given formatter.

impl Error for ChaosError

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 ChaosError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
