Mutually exclusive arguments without error (ignoring previous arguments)

[xbjfk]

Hello,

I want to have arguments that are mutually exclusive, but the behavior should be to ignore all but the last.

Example:
Let's say I had a program with 3 arguments, in an ArgGroup; -a, -b and -c
If I call the program with -a -a -b -c -b, I would like it to be as if I specified only -b.

Is there any way to do this in clap (either with builder or derive)? Thanks.

This is an overrides_with. This is both a builder function and an attribute (like all builder functions).

Awesome, this is exactly what I'm looking for, thank you! Is there a way to do this for an ArgGroup by any chance?

No, I don't believe this can be done with an ArgGroup at this time.
