mnm-store 0.2.2

//! Shared seeding helpers for DB integration tests.
//!
//! These helpers drive the entity layer directly, independently of
//! `mnm-content`, so the store tests have no transitive dependency on the
//! chunker or embedder.
//!
//! Only compiled when `cfg(any(test, feature = "integration"))`.

#![allow(
    clippy::missing_panics_doc, // test helpers are allowed to panic on setup failure
    clippy::too_many_lines,     // fixture setup is verbose by design
    clippy::similar_names,      // doc_a_node / doc_b_node etc. are intentionally parallel names
