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 ...
