Lemma.RuleResult (lemma_engine v0.10.0)

One rule result from Lemma.evaluate/3, as returned in Lemma.Response.results.

Value fields (measure, ratio, number, …) mirror the flattened Rust RuleResultValue. row is a list row reference: its "index" points into Lemma.Response.rows. list holds the items of a list value, each a raw value map (rows carry "row"). explanation is the raw explanation JSON map when present (tagged by "type"); pattern-match on that tag directly.

Summary

Types

t()

Functions

from_map(map)

Builds a Lemma.RuleResult from one value of the decoded Lemma.evaluate/3 JSON "results" map. Optional fields are absent (not null) from the API JSON when unset; Map.get/3 yields nil for those.
