icydb-core 0.267.0

//! Module: lib
//! Responsibility: crate root for the IcyDB core runtime surface.
//! Does not own: canister-facing facade APIs from the public `icydb` crate.
//! Boundary: exposes the engine subsystems used by schema, query, executor, and storage layers.

//! Core runtime for IcyDB: accepted-schema execution, values, storage, and
//! the low-level vocabulary exported through the facade.
#![warn(unreachable_pub)]
// The no-default test target intentionally type-checks shared test/helper
// surfaces whose consuming tests live behind SQL. Keep production and
// all-features dead-code linting strict.
#![cfg_attr(
    all(test, not(feature = "sql")),
    expect(dead_code, reason = "shared test helpers have SQL consumers")
)]
// The base build owns the complete engine-neutral planner/executor substrate.
// SQL is an optional frontend over that substrate and is currently the only
// consumer of some SQL explain, diagnostic, and frontend-extension capabilities,
// so those internal extension points are intentionally dormant without SQL.
