From 76efe0b3dd01025c3fb29428a63ddc3678256ac5 Mon Sep 17 00:00:00 2001 From: AbdelStark Date: Thu, 28 Aug 2025 10:33:17 +0200 Subject: [PATCH] Add performance benchmarking infrastructure Introduces comprehensive performance benchmarking infrastructure for Rustreexo: - Add CI/CD integration with automated benchmarks on pushes and PRs - Implement benchmark coverage for Stump, Proof, and Accumulator operations - Add cross-platform testing on Ubuntu and macOS with environment optimization - Include performance regression detection and statistical analysis - Add timeout management and parameter optimization for CI workflows - Fix clippy warnings across the codebase for improved code quality - Update MSRV to 1.63.0 for criterion compatibility --- .github/workflows/benchmarks.yml |
