Struct Usefulness 

pub struct Usefulness { /* private fields */ }

Bounded usefulness score. This is retrieval utility, not proof or truth.

Implementations

impl Usefulness

pub const MIN: f32 = 0.0

Minimum usefulness score.

pub const MAX: f32 = 1.0

Maximum usefulness score.

pub fn new(score: f32) -> EpistemicResult<Self>

Construct usefulness when the score is in [0, 1].

pub const fn score(self) -> f32

Read the bounded score.

pub fn apply_signal(self, signal: UtilitySignal) -> Self

Apply a utility signal to usefulness only.

Trait Implementations

impl Clone for Usefulness

fn clone(&self) -> Usefulness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Usefulness

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

Formats the value using the given formatter.

impl Default for Usefulness

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Usefulness

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