Module graph_file 

Modularized graph file operations

This directory contains the split modules from the original graph_file.rs to maintain the 300 LOC limit while preserving all functionality.

Module Organization

• buffers.rs: Adaptive read/write buffer management
• validation.rs: File validation and corruption detection
• encoding.rs: Safe header encoding/decoding utilities
• debug.rs: Debug instrumentation and logging
• file_ops.rs: Core file I/O operations
• header.rs: Header encoding/decoding and persistent header operations (future)
• transaction.rs: Transaction lifecycle and commit management (future)
• io_backend.rs: I/O routing and backend selection (future)
• mmap_ops.rs: Memory mapping operations and management (future)
