Module prelude 

One import for the traits whose methods this HAL is used through.

Traits are re-exported anonymously (as _): their methods arrive, their names do not. Types are not re-exported — import those from their own modules.

use gd32e2_hal::prelude::*;          // everything
use gd32e2_hal::prelude::gpio::*;    // or one peripheral at a time

The glob at this level covers every peripheral and takes usart::io for the serial traits. usart::nb is the other choice, never both: their read and write land on the same type, and two traits of one name in scope make every such call ambiguous (E0034).
