vastlint vs rust-doctor

vastlint: VASTlint is a high-performance VAST XML validator built on a pure-Rust core, designed to check ad tags against the IAB Tech Lab VAST specification. It ensures compliance across multiple VAST versions and various other internet standards, helping to prevent malformed tags that cause lost impressions and revenue discrepancies.; rust-doctor: Rust Doctor is a static analysis tool that scans Cargo workspaces using 126 curated rules to identify issues in security, correctness, reliability, performance, maintainability, and dependencies. It operates entirely locally, provides a score, and suggests priority fixes, with integrations for coding agents and CI/CD pipelines.
