itertools

Who should use it

Teams working in the Cargo ecosystem who need extra iterator adaptors, iterator methods, free functions, and macros and value a focused solution.

When not to use it

Consider an alternative if you need to have first-class TypeScript types out of the box, or if a more actively-maintained option better fits your Cargo stack.

Pros

• ✓Zero runtime dependencies — minimal footprint.

Cons

• !No bundled TypeScript types (may require a separate @types package).
• !No license detected — review usage terms before adopting.
