Library
A software library is a reusable collection of code or components that other programs can incorporate or invoke to provide functionality.
Clojure: The Essential Reference
A Clojure library is a source file whose name corresponds to the namespace declaration it contains and which follows conventions for storing and reusing Clojure code.
- How it is used
- Defines the file-backed unit for storing reusable Clojure code and loading it with `require`.
- How deep it goes
- Defines file and namespace conventions, then distinguishes library loading from namespace creation and direct file evaluation.
- Examples
- Uses `clojure.set` loading, a failed `require` of a fileless namespace, and warnings from referring all symbols.
- What you can do after
- Operate/configure it: load file-backed namespaces with `require`, inspect `loaded-libs`, and choose aliases over broad symbol imports.

Idiomatic Rust
A library is a packaged collection of reusable software components that other programs can depend on and call.
- How it is used
- Designs reusable Rust APIs for open-source projects, SDKs, and internal software.
- How deep it goes
- Explains API tradeoffs and demonstrates Cargo setup, integration testing, visibility, documentation, and maintenance practices.
- Examples
- Uses a linked-list crate, external integration test, public iterator types, and compiler errors about private items.
- What you can do after
- Build and maintain focused Rust libraries with usable APIs, external tests, correctness checks, and compatibility-conscious releases.
