/********************************
|
|
* 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.
