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 ...
