Struct Panel 

pub struct Panel {
    pub fuse: Fuse,
    pub diversify: Diversify,
    pub decay: Decay,
}

Host sequence. Clients do not choose this.

Derived from each slot’s own default rather than written out. A second copy of the defaults is a second place to change them, and the two disagreeing means Panel::default() and an unset environment name different panels while both call themselves the default.

Fields

fuse: Fuse

diversify: Diversify

decay: Decay

Implementations

impl Panel

pub fn parse(fuse: &str, diversify: &str) -> Result<Self, UnknownVoter>

A fuse and a diversifier with the shipped decay slot.

pub fn named( fuse: &str, diversify: &str, decay: &str, ) -> Result<Self, UnknownVoter>

pub fn from_env() -> Result<Self, UnknownVoter>

Read PACKSET_FUSE, PACKSET_DIVERSIFY, PACKSET_DECAY. Unset keys take the default. Empty values fail closed.

pub fn from_env_vars( fuse: Option<&str>, diversify: Option<&str>, decay: Option<&str>, ) -> Result<Self, UnknownVoter>

pub fn decay_weight( &self, source: &str, age_days: f64, stability_days: f64, ) -> f64

The factor a fused score is scaled by. age_days is the time since the last review (or the write); stability_days is the review model’s, read only by Fsrs. Evergreen sources stay at one.

pub fn fuse_merge<T>(&self, ballots: &[Ballot<T>], k: usize) -> Vec<T>

where T: Clone + Eq + Hash,

pub fn fuse_scored<T>(&self, ballots: &[ScoredBallot<T>], k: usize) -> Vec<T>

where T: Clone + Eq + Hash,

Fuse scored lists. CombSUM / CombMNZ use the raw scores; rank voters keep list order and ignore the numbers.

pub fn rerank(&self, items: &[Ranked], lambda: f64) -> Vec<String>
