Module scores 

Scorers, rustev.score-views/1 and rustev.scores/1 (spec 041, 3.6 and 3.7).

Scores enter evaluation only as a scores document bound to the views of the same evaluation (R-1): eval computes the views, a host’s scorer scores each entry outside eval, and evaluation refuses a document over other views. Eval stays synchronous and I/O-free; a scorer is a Rust value the host composes in code (D-06).

Modules

reserved

Unscored reasons eval reserves (3.6.1, 3.7, 3.8, 3.9).

Structs

CaseView

What a scorer knows of a case. gold is null for a scorer that does not declare reads_gold (3.7.4).

ProposalView

What a scorer knows of a proposal: the judgment’s action, parameters, derivation and notices.

ScoreEntry

ScoreViews

The views a scorer scores: one entry per comparable proposal case of one evaluation, in manifest order (3.7.1).

Scores

One scorer’s scores over one views document (3.7.2).

ViewEntry

Enums

ScoreOutcome

A score, or why there is none (3.6.1).

Constants

PROPOSAL_VIEW

The tag of a view entry’s subject digest (3.7.1).

SCORES

SCORE_VIEWS

Traits

Scorer

A scorer the host composes in code (3.6, D-06).

Functions

checked

A scorer’s answer as it is recorded (3.7.5): a score outside the output, or an unscored reason that is malformed or reserved for eval, becomes unscored invalid_score, never clamped or passed through.

reason_ok

1 to 64 bytes of [a-z0-9_] (3.6.1).

score_ok

Whether a score lies inside the scorer’s output (3.7.5): a level index of an ordinal scale, or a finite value in a bounded range. Never clamped.

score_views

Calls the scorer once per entry, in order, synchronously (3.7.3), with the case view of scorer_case, and records each answer as checked states.

scorer_case

The case view a scorer is handed (3.7.4): the entry’s, with gold null unless the scorer declares reads_gold.
