Struct AssertionStats 

pub struct AssertionStats {
    pub total_checks: usize,
    pub successes: usize,
}

Statistics for a tracked assertion.

Records the total number of times an assertion was checked and how many times it succeeded, enabling calculation of success rates for probabilistic properties in distributed systems.

Fields

total_checks: usize

Total number of times this assertion was evaluated

successes: usize

Number of times the assertion condition was true

Implementations

impl AssertionStats

pub fn new() -> Self

Create new assertion statistics starting at zero.

pub fn success_rate(&self) -> f64

Calculate the success rate as a percentage (0.0 to 100.0).

Returns 0.0 if no checks have been performed yet.

Calculate the success rate as a percentage (0.0 to 100.0).

pub fn record(&mut self, success: bool)

Record a new assertion check with the given result.

Increments total_checks and successes (if the result was true).

Trait Implementations

impl Clone for AssertionStats

fn clone(&self) -> AssertionStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssertionStats

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

Formats the value using the given formatter.

impl Default for AssertionStats

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for AssertionStats

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