This chapter delves into the technical aspects of HTTP handling with a Rust-based server, focusing on the use of the hyper library for reliable HTTP handling and the unique architecture of the Grannyon server with independent loops in Python and Rust. Discussions include runtime modes, threading options, and their impact on performance, scalability, and resource allocation for Python and Rust components. Additionally, the chapter touches on asynchronous code challenges in Python, memory consumption issues, process management complexities, and future plans for feature enhancements in the server.
