Скачать или смотреть Rust 101 - 36: What async and await really do

Attempting to explain as slowly as possible what actually happens when the compiler finds an async function containing awaits: it writes a poll method for you to create something that implements Future. The generated poll method polls the Futures you asked to await, in order. The interesting bit is that this generated thing that implements Future and has a poll method needs to own the things it refers to, which is what leads to some of the most confusing error messages you see when writing this kind of code.
