Struct UtilityScore 

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

Fixed-point utility used only for deterministic ordering.

The value is not a probability. It is calculated as gain * confidence * business_value / cost / risk using the integer units exposed by each input type.

Implementations

impl UtilityScore

pub const ZERO: Self

Zero utility.

pub const MIN_POSITIVE: Self

Smallest positive utility accepted by a default planning context.

pub const fn from_units(units: u64) -> Self

Creates a threshold or persisted score from raw utility units.

pub const fn units(self) -> u64

Returns raw fixed-point utility units.
