PyCyBase

Common C / Cython dual interfaces for Python HFT Projects.

Overview

This package provides low-level allocator infrastructure shared across HFT projects:

• c_allocator_protocol — Unified memory allocation protocol supporting heap, shared memory (SHM), and raw malloc backends with ref-counting and vigilant mode.
• c_shm_allocator — POSIX shared-memory backed page allocator with fixed-address virtual region mapping for cross-process pointer stability.
• c_heap_allocator — In-process heap allocator with free-list reuse and auto-growing pages.

Installation

pip install -e .

Usage

from cbase.allocator_protocol.c_allocator_protocol import AllocatorProtocol, AP_SHARED

with AP_SHARED:
    alloc = AllocatorProtocol(1024)
    alloc.buf[0] = b'x'
