An extension class to allocate memory easily with cython.

This extension class started as part of the Sage software.

It provides a single extension class MemoryAllocator with cdef methods

• malloc,
• calloc,
• allocarray,
• realloc,
• reallocarray,
• aligned_malloc,
• aligned_calloc,
• aligned_allocarray.

Memory is freed when the instance of MemoryAllocator is deallocated. On failure to allocate the memory, a proper error is raised.

This project uses meson-python for its build backend. A typical editable install looks like:

  python -m pip install -e .
