Cargo Workflows

Covers the practical Cargo workflows you'll need beyond basic builds: setting up workspaces with shared dependencies, managing feature flags without shooting yourself in the foot, writing build.rs scripts that actually rebuild when they should, and configuring CI caching that works. Includes cargo-nextest for faster test runs, cargo-deny for dependency auditing, and the workspace.dependencies pattern that keeps version management sane across multi-crate projects. The feature resolver gotchas alone (additivity, resolver v2) will save you debugging time. Solid reference if you're moving past single-crate projects or trying to speed up your CI pipeline without guessing at cache configurations.

Cargo Workflows

Purpose

Guide agents through Cargo workspaces, feature management, build scripts (build.rs), CI integration, incremental compilation, and the Cargo tool ecosystem.

Triggers

"How do I set up a Cargo workspace with multiple crates?"
"How do features work in Cargo?"
"How do I write a build.rs script?"
"How do I speed up Cargo builds in CI?"
"How do I audit my Rust dependencies?"
"What is cargo nextest and should I use it?"
