Need help for example 12 Typed Value

[jemagnie]

Hi,

I'm new in rust, and i hope someone could help me with this issue.
When i copy the example 12 typed value and i try to build i have this error:

.arg("<seq>... 'A sequence of whole positive numbers, i.e. 20 25 30'")
 ^^^ the trait `std::convert::From<&str>` is not implemented for `clap::args::arg::Arg<'_, '_>`

example 12: https://github.com/clap-rs/clap/blob/master/examples/12_typed_values.rs

i can't understand why and how to resolve it

Thanks :)

This is because you are trying to build an example in master (we're working on releasing 3.0 which is not backward compatible) with 2.33. If you're seeking for 2.x examples, you need to checkout the corresponding tag:
