Struct DeterministicScore 

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

Fixed-point score wrapping an i64 scaled by 2^32.

Implementations

impl DeterministicScore

pub const MAX: DeterministicScore

Highest representable score (i64::MAX); maps to +Infinity in float conversion.

pub const MIN: DeterministicScore

Reserved sentinel at i64::MIN; never produced by arithmetic or float conversion.

pub const NEG_INF: DeterministicScore

Lowest reachable runtime score (i64::MIN + 1); underflow and -Infinity clamp here.

pub const ZERO: DeterministicScore

Score of exactly zero.

pub const fn from_raw(raw: i64) -> DeterministicScore

Construct from a raw i64 without validation. Passing i64::MIN creates the reserved sentinel.

pub const fn from_raw_saturating(raw: i64) -> DeterministicScore

Construct from a raw i64, mapping i64::MIN to NEG_INF.

pub const fn from_raw_checked(raw: i64) -> Option<DeterministicScore>

Construct from a raw i64, returning None if raw == i64::MIN.

pub const fn to_raw(self) -> i64

Return the underlying i64 fixed-point representation.

pub fn from_f64(val: f64) -> DeterministicScore

Convert an f64 to a DeterministicScore (NaN → ZERO, ±Inf → MAX/NEG_INF).

pub fn from_f32(val: f32) -> DeterministicScore

Convert an f32 to a DeterministicScore via from_f64.

pub fn to_f64(self) -> f64

Convert this score back to f64 (sentinels map to ±Infinity).

pub const fn is_infinite(self) -> bool

Return true if the score is the MAX or NEG_INF sentinel.
