Action Summary

The cargo-perf GitHub Action is designed to perform static analysis on Rust code to identify issues related to async correctness and runtime performance. It automates the detection of common bugs such as blocking operations in async contexts, potential deadlocks, and inefficient code patterns like unoptimized loops or resource mismanagement. Additionally, it integrates seamlessly into CI pipelines, with features like strict rule enforcement, SARIF output for GitHub Code Scanning, and optional auto-fixing capabilities to streamline code quality and improve performance.
