SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Rust projects often grow target/ directories large: 2-10 GB per project, leading to wasted disk space and long rebuild times.

Core Features & Use Cases

Caching compilation with sccache to avoid re-building unchanged code.
Disk management guidance: using per-project target directories and a shared cache to balance speed and disk usage.
Use Case: multi-crate Rust workspaces benefit from cached artifacts across crates, reducing CI build times and local rebuilds.

Quick Start

Install sccache and configure cargo to use it so Rust builds are cached and disk usage is reduced.

FAQPage Schema

How do I speed up Rust builds in CI pipelines?▼

Speed up Rust builds by installing sccache and configuring Cargo to use the sccache wrapper, caching compilation artifacts across projects to avoid re-building unchanged code in CI pipelines.

What's the best way to manage large target directories in Rust workspaces?▼

Manage large Rust target directories by using per-project target directories alongside a shared cache, balancing disk usage and compilation speed across multi-crate Rust workspaces.

How does sccache avoid recompiling unchanged Rust code?▼

Sccache avoids recompiling unchanged Rust code by caching compilation artifacts, allowing multiple crates within a workspace to reuse previously built outputs instead of regenerating them.

Do I need to install sccache to use cache-aware compilation for Cargo?▼

Yes, you need to install sccache and configure Cargo to use the sccache wrapper and a specified cache location to enable cache-aware compilation for Rust projects.

Can I share Rust compilation artifacts across different projects?▼

Yes, you can share Rust compilation artifacts across different projects by configuring Cargo to use sccache, which caches and reuses the compilation outputs across multi-crate workspaces.

Why does my multi-crate Rust workspace take so long to rebuild?▼

Multi-crate Rust workspaces take a long time to rebuild because target directories grow to 2-10 GB, forcing recompilation of unchanged code; using sccache solves this by caching artifacts.
