Struct databake::converter::AsStaticStr

#[repr(transparent)]
pub struct AsStaticStr<T>(pub T)
where
    T: AsRef<str>;

Let Bake output a &'static str for anything that can be AsRef<str>.

It can be helpful if the type needs to be constructed (e.g. String, Cow<str>) but should result in a &'static str.

This requires that the crate using the generated data needs a different struct.

use databake::{Bake, converter::AsStaticStr};

#[derive(Bake)]
#[databake(path = my_crate)]
struct Data {
    number: usize,
    string: AsStaticStr<String>, // can be written as StringAsStaticStr
}

let data = Data {
    number: 6,
    string: 6.to_string().into()
};

assert_eq!(
    data.bake(&Default::default()).to_string(),
    r#"my_crate :: Data { number : 6usize , string : "6" , }"#
);

mod my_crate {
    struct Data {
        number: usize,
        string: &'static str,
    }
}
