Struct FailureProbability 

pub struct FailureProbability(/* private fields */);

Probability of injecting read/write failures for chaos testing.

FailureProbability represents a value in the range [0.0, 1.0] where 0.0 means never inject failures and 1.0 means always inject failures.

Examples

use eventcore_testing::chaos::FailureProbability;

let never = FailureProbability::try_new(0.0).expect("0.0 is valid");
let sometimes = FailureProbability::try_new(0.5).expect("0.5 is valid");
let always = FailureProbability::try_new(1.0).expect("1.0 is valid");

// Values outside [0.0, 1.0] are rejected
assert!(FailureProbability::try_new(1.5).is_err());
assert!(FailureProbability::try_new(-0.1).is_err());

Implementations

impl FailureProbability

pub fn try_new(raw_value: f32) -> Result<Self, FailureProbabilityError>

impl FailureProbability

pub fn into_inner(self) -> f32

Trait Implementations

impl Clone for FailureProbability

fn clone(&self) -> FailureProbability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FailureProbability

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

Formats the value using the given formatter.

impl Display for FailureProbability

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

Formats the value using the given formatter.

impl From<FailureProbability> for f32

fn from(value: FailureProbability) -> Self

Converts to this type from the input type.

impl PartialEq for FailureProbability

fn eq(&self, other: &FailureProbability) -> 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.

impl PartialOrd for FailureProbability

fn partial_cmp(&self, other: &FailureProbability) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
