query_planning/lib.rs
1//! Backend-neutral native query planning, proof, and admission contracts.
2//!
3//! Published as an Algeon implementation dependency. Applications use
4//! [`algeon-datafusion`](https://docs.rs/algeon-datafusion) and its re-exports.
5//! See the [API documentation boundary](https://algeon.dev/design#api-documentation).
6//!
7//! This crate contains no dependency on DataFusion or RAPIDS components.
8//! The resolved dependency closure across all feature combinations excludes both,
9//! as validated by `scripts/ci/check_dependency_direction.py`.
10//! Capabilities that depend on backend execution semantics, such as type
11//! representation, expression binding, or kernel output type inference, are
12//! mediated through the [`backend::BackendCapabilities`] trait and supplied
13//! via [`backend::AnalysisContext`].
14//!
15//! The crate performs no file or network I/O. File metadata and decoded statistics
16//! are provided externally through [`source::SourceFooterFacts`] and the
17//! pruning resolvers in [`optimizer`].
18//!
19//! While dependency direction is structurally enforced by CI scripts, build
20//! behavior on hosts lacking RAPIDS or CUDA toolchains is not validated by the
21//! workspace test harness.
