Colla

A header-only memory allocator library written in C++, compatible with STL containers.

Features

• No dependencies, header-only.
• Compatible with STL containers.
• Multiple allocators:
  • colla::FixedBufferAllocator<T>: Allocates memory from a buffer of fixed size.
  • colla::ArenaAllocator<T>: Allocates memory from a pre-allocated arena.
  • colla::SlabAllocator<T>: Allocates memory in slabs from a cache, allocating another cache if all are full.

Usage

You can look into examples/ for example usage of each allocator. You can build them by turning on the BUILD_EXAMPLES option in CMake.

Compatibility

Due to being backed by mmap, slab and arena allocators work only on POSIX systems.
