v0.10.0

💾 Memory-Based Limits!

Version 0.10.0 introduces memory-aware caching controls:

New Features:

• 💾 Memory-Based Limits - Control cache size by memory footprint
• 📏 max_memory Attribute - Specify memory limit (e.g. max_memory = "100MB")
• 🔄 Combined Limits - Use both entry count and memory limits together
• ⚙️ Custom Memory Estimation - Implement MemoryEstimator for precise control
• 📊 Improved Statistics - Monitor memory usage and hit/miss rates together

Breaking Changes:

• Default policy remains LRU - No change, but now with memory limits!
• MemoryEstimator usage - Custom types with heap allocations must implement MemoryEstimator

Quick Start:

// Memory limit - eviction when total size exceeds 100MB
#[cache(max_memory = "100MB")]
fn large_object(id: u32) -> Vec<u8> {
    vec![0u8; 512 * 1024] // 512KB object
}

// Combined limits - max 500 entries OR 128MB
#[cache(limit = 500, max_memory = "128MB")]
fn compute(x: u64) -> u64 { x * x }

What's Changed

• Add memory-based cache limits by @josepdcs in #25
