Crate openeruka 

openeruka

Open core types and traits for the Eruka context memory system.

Eruka is a structured, knowledge-state-aware memory layer for AI agents. This crate provides the vocabulary every consumer needs: types for fields, entities, edges, and the epistemological states that make Eruka different.

Quick start

use openeruka::{KnowledgeState, FieldPath, Confidence};

let path = FieldPath::new("identity/company_name").unwrap();
assert_eq!(path.as_str(), "identity/company_name");

// The core invariant: Confirmed facts resist Inferred overwrites
assert!( KnowledgeState::Confirmed.can_overwrite(&KnowledgeState::Inferred));
assert!(!KnowledgeState::Inferred.can_overwrite(&KnowledgeState::Confirmed));

let c = Confidence::new(0.9);
assert_eq!(c.value(), 0.9);
