[0.3.0] - 2025-11-23

Changed

• BREAKING: BufferPool::get() now returns PooledBuffer instead of Vec<u8>
  • PooledBuffer implements Deref<Target = Vec<u8>> for transparent access
  • Buffers automatically return to pool when dropped (RAII pattern)
  • No more manual pool.put() calls needed
• BREAKING: BufferPool::put() is now internal-only (pub(crate))
  • Users should rely on automatic return via Drop
  • For explicit early return, use drop(buffer)

Added

• New PooledBuffer type providing automatic buffer return via Drop trait
• PooledBuffer implements:
  • Deref<Target = Vec<u8>> and DerefMut for transparent Vec API access
  • AsRef<[u8]> and AsMut<[u8]> for slice conversions
  • Debug with buffer length and capacity
  • Send and Sync for thread safety
• Configurable eviction policies (LIFO, ClockPro) for fine-tuned performance
• Profiling binaries for performance analysis:
  • ml_checkpoint_loader: ML model loading simulation
  • network_server: Multi-threaded network server simulation
  • file_pipeline: File processing pipeline simulation
  • stress_test: High-stress workload testing
• Modularized codebase with separate modules for buffer, config, pool, and utilities

Fixed

• Removed all unsafe code blocks for improved safety
• Fixed all clippy warnings and formatting issues
• Improved code organization and documentation

Migration Guide

Before (v0.2.x):

let buf = pool.get(1024);
// use buf
pool.put(buf); // Manual return

After (v0.3.0):

let buf = pool.get(1024);
// use buf
// Auto-returns on drop!

// For explicit early return:
drop(buf);
