Struct AcceptanceCalibration 

pub struct AcceptanceCalibration {
    pub drafter: DrafterKey,
    /* private fields */
}

2026-10-04: How likely a draft is to be accepted, from the drafter’s top-1 log-probability for it, fitted on one drafter (DrafterKey); and per-position priors for drafts whose confidence was not measured. A draft is accepted only if every draft before it was, so a chain’s expected accepted length is the sum of the running products.

Fields

drafter: DrafterKey

Implementations

impl AcceptanceCalibration

pub fn fit( drafter: DrafterKey, edges: &[f32], accepted: &[u64], rejected: &[u64], steps: &BTreeMap<(usize, usize), u64>, ) -> Result<Self, String>

2026-10-04: The calibration of drafter from per-bucket reached-draft outcomes (edges ascending, accepted[i] and rejected[i] in bucket i) and verify steps by (drafts, accepted).

pub fn render(&self) -> Result<String, String>

2026-10-04: The calibration file text Self::parse reads, checked by reading it back.

impl AcceptanceCalibration

pub fn parse(text: &str) -> Result<Self, String>

2026-10-04: Parses and validates a calibration file: as many probabilities as edges, edges strictly ascending with the last at least 0, every probability in 0..=1, at least one position prior.

pub fn p_given_lp(&self, lp: f32) -> f64

2026-10-04: P(accept) of a draft whose top-1 log-probability is lp.

pub fn prior(&self, j: usize) -> f64

2026-10-04: The prior for draft position j (1-based); positions past the last fitted one take the last prior.

pub fn expected_accepted(&self, lps: &[f32], k: usize) -> f64

2026-10-04: Expected accepted drafts of a chain whose drafts have confidences lps (missing entries take the position prior), counting only the first k.

Trait Implementations

impl Clone for AcceptanceCalibration

fn clone(&self) -> AcceptanceCalibration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AcceptanceCalibration

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

Formats the value using the given formatter.

impl PartialEq for AcceptanceCalibration

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