Derive Macro BuilderLite

#[derive(BuilderLite)]
{
    // Attributes available to this derive:
    #[builder_lite]
}

Automatically implement the Builder Lite pattern for a struct.

This will create an impl which contains methods for each field of a struct, allowing users to easily set the values. The generated methods will be the field name prefixed with with_, and calls to these methods can be chained as needed.

Example

#[derive(Default)]
enum MyEnum {
    #[default]
    A,
    B,
}

#[derive(Default, BuilderLite)]
#[non_exhaustive]
struct MyStruct {
    enum_field: MyEnum,
    bool_field: bool,
    option_field: Option<i32>,
}

MyStruct::default()
    .with_enum_field(MyEnum::B)
    .with_bool_field(true)
    .with_option_field(-5);
