Dependency Resolution With Multiple Versions Tutorials The Rust Some crates depend on older versions, others depend on newer versions, and no amount of "frameworks" can solve this, because you simply can't force everyone to always upgrade their libraries' dependencies at the same time, throughout the entire ecosystem, immediately, and without exception. One of cargo’s primary tasks is to determine the versions of dependencies to use based on the version requirements specified in each package. this process is called “dependency resolution” and is performed by the “resolver”.

Detecting Whether Dependency Package Enabled Its Feature The Rust I have dependency x in my project that depends on z and dependency y that also depends on z but version requirements are different for x and y. also i use z itself in my project and want it to be the latest version possible. Like npm and composer, cargo allows you to specify a range of dependency versions that your project is compatible with based on the compatibility rules of semantic versioning. this allows you to describe one or more versions that are (or might be) compatible with your code. If you're working on a project with multiple developers, you should commit the cargo.lock file to your version control system. you can use cargo update to update the cargo.lock file with the latest (compatible) versions of all your dependencies. you can also specify a dependency using a path. As for building multiple versions of the same crate, it's practically unavoidable. this is a feature of cargo, which allows the application to build, instead of creating a real "dependency hell" that causes builds to fail because of breaking api changes.

When multiple packages specify a dependency for a common package, the resolver attempts to ensure that they use the same version of that common package, as long as they are within a semver compatibility range. Rust’s cargo is opinionated as to how dependencies are resolved and selected. when two dependencies in a programs build depend on the same crate with different patch versions, cargo will resolve to a single version so that only one version of the crate is built into the program. Rust will embed multiple different versions of the same dependency for usage by other dependencies. all this is transparent. you are never limited to only one version for each crate. there can be multiple versions of the same crate in your build, and cargo automatically manages them. With several crates in a workspace, it’s common to face version conflicts, especially when different crates depend on different versions of the same dependency.
