Module mmap 

Memory-Mapped File Serving

Provides zero-copy file serving using memory-mapped I/O for improved performance with large tensor files. This module enables efficient serving of tensors without loading the entire file into memory.

Features

• Zero-copy serving - Direct memory mapping without buffer allocation
• Lazy loading - Map files only when accessed
• Range request support - Efficient partial file serving
• Platform optimizations - Uses OS-level optimizations (sendfile, etc.)

Safety

Memory mapping is inherently unsafe as it involves raw pointer access. This module provides a safe wrapper that ensures proper lifetime management and error handling.

Structs

MmapCache

A simple cache for memory-mapped files

MmapConfig

Platform-specific optimization hints

MmapFile

A handle to a memory-mapped file

Enums

MmapError

Errors that can occur during memory-mapped operations
