## What it is
Cargo is the official package manager and build tool for the Rust language. It downloads dependencies, compiles projects, runs tests, creates distributable packages, and publishes crates to the crates.io registry.

## Use cases
- manage rust project dependencies
- build and compile a rust crate
- publish a package to crates.io
- run rust tests and benchmarks
- create a new rust project scaffold
- pin dependency versions with a lockfile
- manage rust workspaces with multiple crates

## When to choose
- you are developing any Rust project, from scripts to large workspaces
- you need reproducible builds with a lockfile and vendored dependencies
- you want to publish or consume crates from crates.io

## When to avoid
- you are not working with the Rust language
- you need a general-purpose polyglot build system like Bazel or Pants
