1//! Standard Lean service layer for Rust applications embedding Lean 4.
2//!
3//! This crate is the standard service layer built on top of the typed FFI
4//! crate shipped by [`lean-rs`](https://docs.rs/lean-rs). It owns:
5//!
6//! - The high-level [`LeanHost`] / [`LeanCapabilities`] / [`LeanSession`]
7//!   trio, plus the [`SessionPool`] / [`PooledSession`] reuse helper and
8//!   [`LeanProgressSink`] for live progress from long-running calls.
9//! - The host-defined evidence / kernel-outcome / elaboration / meta
10//!   value types: [`LeanEvidence`], [`LeanKernelOutcome`],
11//!   [`ProofSummary`], [`LeanElabOptions`], [`LeanElabFailure`], the
12//!   `meta::*` service surface.
13//! - The capability contract: 28 mandatory + 9 optional `lean_rs_host_*`
14//!   `@[export]` Lean shims bundled with this crate and loaded alongside the
15//!   consumer capability dylib.
16//!
17//! Downstream applications that only need to call `@[export]` Lean functions
18//! with typed arguments and no shim contract
19//! should depend on `lean-rs` directly and skip this crate.
