Crate qail_core 

QAIL AST Kernel.

Build database intent as typed AST, not application-assembled SQL strings. The AST can then be validated, policy-checked, formatted, encoded for a driver, or inspected by tooling.

Main concepts:

• Qail: the primary command builder for get, add, set, del, put, merge_into, CTEs, filters, projections, and returning clauses.
• access: native table/operation/column policy checks.
• rls: tenant/user/super-admin execution context witnesses.
• migrate: schema.qail parsing, diffing, and migration model types.
• build: source scanner helpers for stale schema references and N+1 diagnostics.

use qail_core::prelude::*;

let ctx = RlsContext::tenant("018f6a60-4d5f-7a9d-9f4c-7dd8c338f1d2");
let cmd = Qail::get("users")
    .columns(["id", "email"])
    .eq("active", true)
    .with_rls(&ctx)?;
