Cargo Semver Checks is a Rust tool by Predrag Gruevski that is tackling the problem of broken dependencies that cost developers time when trying to upgrade dependencies. Predrag’s work shows how automated checks can catch breaking changes before they’re released, potentially saving projects from unexpected failures and making dependency updates less painful across the entire Rust ecosystem. These problems occur even among the most experienced, careful Rust developers who understand the consequences of breaking semantic versioning.
