Understanding Pinning and Self-Referential Futures in Rust

In Rust, an async fn functions as a generator for a state machine. Rather than executing the logic immediately, it returns an anonymous type that implements the Future trait. use std::future::Future; async fn compute_value() -> u32 { 123 } The semantics of a Future represent a value that might become available eventually. These objects ...

Understanding Box::pin in Rust Async Recursion

In Rust, Box::pin serves as a critical tool for handling recursive asynchronous functions where the compiler cannot determine the size of the returned Future. To fully grasp its application, we need to explore several foundational concepts: asynchronous functions, Future traits, and dynamically sized types. The Core Issue: Recursive Futures and ...
