Exploring Rust Crates

Generate and use Rust documentation to understand crate APIs, structure, and code organization in the HASH workspace.

Generating Documentation

For a Specific Package

cargo doc --no-deps --all-features --package <package-name>

For the Entire Workspace

cargo doc --no-deps --all-features --workspace

Key Flags

• --no-deps: Document local code only (faster, less noise)
• --all-features: Include all feature-gated APIs
• --package <name>: Target a specific crate
• --workspace: Document all crates in the workspace
• --document-private-items: Include internal implementation details

What Generated Docs Provide

1. Crate organization - Module hierarchy and component relationships
2. Public API surface - All public functions, types, traits, and constants
3. Usage examples - Code examples from doctest blocks
4. Error documentation - Documented error conditions and handling
5. Type relationships - Trait implementations, type aliases, associated types

Viewing Documentation

Docs are generated at:

target/doc/<crate_name>/index.html

Tips

• Generate docs before diving into unfamiliar Rust code
• Cross-reference # Errors sections for error handling patterns
• Look for # Examples sections for idiomatic usage patterns
