Is it possible to do a 'partial' fake?

I'm wondering if there's a way to be able to set some subset of fields to specific values, and then be able to use fake-generated values for the rest of the fields? Kinda like how with default you can do something like:

let my_struct = MyStruct {
    field_one: "hello",
    ..Default::default()   
};

[cksac]

you can use #[dummy(expr = "xxx")]

#[allow(dead_code)]
#[derive(Debug, Dummy)]
struct ExprStruct {
    #[dummy(faker = "1..100")]
    pub product_id: usize,
    #[dummy(expr = "\"Base\".into()")]
    pub fixed_value: String,
}

Sorry, I was referring to being able to pass a specific value in when creating an instance, not when defining the struct, is that possible?

[cksac]

you can try following. e.g.

let my_struct = MyStruct {
    field_one: "hello",
    ..Faker.fake()
};

Perfect! Exactly what I needed. Thanks!
