A macro, or two, to simplify usage of builder pattern on structs.
use builder_option::Builder;
#[derive(Debug, Builder)]

pub field: bool,
pub another: Option<bool>,
pub optional: Option<String>,
}
fn main() -> Result<(), dyn std::error::Error> {

.with_field(true)
.with_another(false),
.build()?;
assert!(client.field);
assert_eq!(client.another, false);
