LibExcessive Wiki

LibExcessive is a high-performance C++ library designed for data-heavy applications. It provides RAII-based file I/O, on-disk data structures, and efficient memory management utilities.

Core Features

• High-Performance I/O: RAII-based file handles, thread-safe operations, and seamless memory mapping.
• On-Disk Data Structures: Persistent B-Trees for efficient storage and retrieval.
• Fixed-Width Bigints: Non-allocating large integer arithmetic (128, 256 bits, etc.).
• Memory Management: Smart pointers with Copy-on-Write (COW) and custom allocator friendliness.
• Containers: Simple, efficient alternatives to standard library containers.
