fast_blank

fast_blank is a Ruby C extension that delivers a high-performance alternative to Active Support's `String#blank?` method. It offers significant speed improvements while maintaining compatibility with Ruby's standard behavior for determining if a string is empty or contains only whitespace. ## Key Features - **Performance Optimized** — Provides 1.2–20x faster execution compared to Active Support's implementation, depending on string length. - **Zero String Allocation** — Operates without allocating additional strings, reducing garbage collection overhead. - **Full Compatibility** — Includes `blank_as?` method for 100% compatibility with Active Support's Unicode-aware `blank?` behavior. - **MRI & Rubinius Support** — Compatible with MRI Ruby 1.9.3 through 2.2 and Rubinius 2.x. ## Philosophy fast_blank prioritizes raw performance and minimal memory overhead while maintaining behavioral parity with Ruby's native string handling, making it an ideal drop-in replacement for performance-critical applications.
