# This Dockerfile is used to build a Docker image for the aaprop project
# The image is built in two stages:
# 1. The first stage uses the official Rust image as the builder image
#    It builds the Rust project and creates a binary
# 2. The second stage uses the official Debian image as the base image
#    It copies the binary from the builder image and sets it as the entry point of the container

# Use the official Rust image as the builder image
# Use the 1.75 version of the Rust image since it's the MSRV (Minimum Supported Rust Version) for the aaprop project
