/********************************
* Why do we need this wrapper?
********************************
*
* The command `rustup component list` does not work with custom toolchains:
* > error: toolchain 'magisk' does not support components
*
* However, this command is used by several IDEs to determine component
* availability, such as clippy, rustfmt etc.
* In this program, we use the output of the command with the nightly
* channel if any `component` command failed.
