v0.1.2 - Idiomatic Builder Pattern & Memory Pinning

What's New

Idiomatic Rust Builder Pattern

• Added BufferPool::builder following tokio/rayon style
• Removed non-idiomatic preset methods
• Made PoolConfig private (internal implementation)

Memory Pinning Support

• Added pinned_memory builder method
• Always available (no feature flags needed)
• Pre-allocates and pins buffers for optimal performance
• Graceful fallback if pinning fails

Improved Test Coverage

• 12 comprehensive tests (was 5)
• New tests: builder API, pinned memory, concurrent access, edge cases
• All tests passing, clippy clean

Rust Best Practices

• const fn for builder methods
• Proper must_use annotations
• Modern format strings
• Optimized allocations

API Changes

New:

• BufferPool::builder
• Builder::min_buffer_size
• Builder::num_shards
• Builder::tls_cache_size
• Builder::max_buffers_per_shard
• Builder::pinned_memory

Removed:

• PoolConfig public API (now private)
• PoolConfig preset methods

Migration Guide

Before:
let pool = BufferPool::with_config(PoolConfig::default().with_min_buffer_size(512 * 1024));

After:
let pool = BufferPool::builder().min_buffer_size(512 * 1024).build();
