Crate rpytest_daemon 

rpytest-daemon: Pure Rust daemon for test execution and management.

This crate provides a high-performance Rust daemon for rpytest that handles:

• IPC communication with the CLI via NNG
• Test collection using native AST parsing
• Inventory and state management with sled storage
• Test scheduling and execution
• Flakiness tracking and fixture management

Features

• embedded-python (default): Use PyO3 to embed Python for direct pytest execution, eliminating subprocess overhead.
• subprocess-only: Disable embedded Python, always use subprocess execution.
