# There are two kinds of continuous integration jobs in this project: | |
# | |
# - Every code submission or master push passes continuous integration on the | |
# minimal supported Rust version and the current stable Rust version. | |
# - Two times a month, a scheduled job makes sure that the code remains | |
# compatible and lint-free on upcoming Rust toolchains (beta and nightly). | |
