Crate denet 

Denet: A high-performance process monitoring library

Denet provides accurate measurement of process resource usage, including CPU, memory, disk I/O, and network I/O. It’s designed to be lightweight, accurate, and cross-platform.

Architecture

The library is organized into focused modules:

• core: Pure Rust monitoring functionality
• monitor: Metrics types and summary generation
• config: Configuration structures and builders
• error: Comprehensive error handling
• cpu_sampler: Platform-specific CPU measurement
• python: PyO3 bindings (when feature is enabled)

Platform Support

CPU measurement strategies:

• Linux: Direct procfs reading - matches top/htop measurements
• macOS: Will use host_processor_info API and libproc (planned)
• Windows: Will use GetProcessTimes and Performance Counters (planned)
