oxiz-proof 0.2.2

Proof generation and checking for OxiZ SMT solver
Documentation
//! # oxiz-proof
//!
//! Proof generation and checking for the OxiZ SMT solver.
//!
//! This crate provides machine-checkable proof output in various formats,
//! enabling verification of solver results by external proof checkers.
//!
//! ## Beyond Z3
//!
//! While Z3 supports generic proofs, OxiZ aims to generate **machine-checkable
//! proofs** (Alethe, LFSC) by default, making it more suitable for certified
//! verification workflows.
//!
//! ## Supported Formats
//!
//! - **DRAT**: For SAT core proofs
//! - **Alethe**: SMT-LIB proof format
//! - **Carcara**: Proof checker compatibility for Alethe format
//! - **LFSC**: Logical Framework with Side Conditions
//! - **Coq**: Export to Coq proof assistant
//! - **Lean**: Export to Lean theorem prover (Lean 3 & 4)
//! - **Isabelle**: Export to Isabelle/HOL
//! - **Theory**: Theory-specific proof steps
//! - **Checker**: Proof validation infrastructure
//! - **PCC**: Proof-carrying code generation
//! - **Merge**: Proof merging and slicing utilities
//! - **Diff**: Proof comparison and similarity metrics
//! - **Normalize**: Proof normalization for canonical representation
