Set default of field to make it optional without Option #119

Closed tontinton closed 1 month ago

tontinton commented 1 month ago

This will allow:

#[builder]
struct Test {
  #[builder_default=true]
  a: bool
}

Also for functions.

Exact syntax can be changed, doesn't really matter.

Hi, thank you for creating the issue! If you are looking for an attribute that makes the member optional, then there is such an attribute. It's called #[builder(default)].

If you have any ideas how to improve its discoverability, I'd be happy to hear them 🐱

I found this one easy to discover in the docs, fwiw

Veetaha commented 1 month ago

@tontinton see my comment https://github.com/elastio/bon/issues/119#issuecomment-2337546162, if that answers you question then close the issue.

I'll close the issue myself If I won't receive feedback from @tontinton
