range-v3 is a C++14/17/20 range library that extends the STL with composable views, actions, and range-based algorithms. It served as the basis for the C++20 std::ranges standardization proposal (P0896R4).

Use cases

• compose lazy data transformations with pipe syntax in C++
• replace iterator-pair STL algorithm calls with range-based overloads
• chain filtering, transforming, and slicing of containers
• eagerly mutate containers with actions
• write terse readable data-processing pipelines in C++

When to choose

• you need composable lazy views on C++ sequences
• you target C++14/17 and want std::ranges-like functionality
• you want the reference implementation behind C++20 ranges

When to avoid

• you can use std::ranges directly on C++20
• you need extensive documentation and tutorials (docs are incomplete)
• you need a license suitable for strict corporate compliance (license is non-standard)
