    A Rust library that provides access to the Raspberry Pi's GPIO, I2C, PWM, SPI and UART peripherals.

    Hi, I'm trying to learn Rust and one of my project for that is to use Rust to read and react to a rotary encoder connected to GPIO pins on a Raspberry Pi. Using the RPPAL library, everything works extremely great. However, the code for setting the interrupt callbacks look rather crude to me for some reason.
