pub const fn interesting_trials(self) -> usize

Oracle evaluations that returned Interesting.

pub const fn not_interesting_trials(self) -> usize

Oracle evaluations that returned NotInteresting.

pub const fn unresolved_trials(self) -> usize

Oracle evaluations that returned Unresolved.

Trait Implementations

impl Clone for DdminStats

fn clone(&self) -> DdminStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DdminStats

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

Formats the value using the given formatter.

impl Default for DdminStats

fn default() -> DdminStats

Returns the “default value” for a type.

impl PartialEq for DdminStats

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