Is there a way to require some argument only if both(or more) conditions are satisfied?

[zzz845zz]

I want to get some advice how to express and(&&) condition using clap.

e.g. Assume arg1, arg2, arg3 exist and all have takes_value=true

• I want to force to use arg3 only if arg1=1 and arg2=2
• I want to force not to use arg3 if arg1=1 or arg2=2 are not satisfied

You can try to check the other require* methods shown in the documentation. If none of them work, then this feature is not supproted.

And please create a feature request issue if not supported.

For more simply, The examples below are what i want

If (arg1==1 && arg==2) {
    // use arg3!!
} else {
    // don't use arg3!!
}

If (extra=="val" && option=="spec") {
    // use cfg!!
} else {
    // don't use cfg!!
}
