Finding index of a one of number of characters

1

Having string let's say 01c23a45b6, what is the most idiomatic way to find the position of either 'a', 'b' or 'c' char in that string?

2 
println!("{:?}", "0123a456".find("a"));

Hi and thanks.
And how to go about finding one of let's say few, that is I would like to find first of (a,b or c)?

Please read the documentation for str::find(). It explicitly states that:

So, you can use ['a', 'b', 'c'].as_slice() in the argument.

I think as slice is being called on unstable fixed_size_array?

You can use as_ref() or &['a', 'b', 'c'][..] as well, it doesn't matter.
