Attribute Macro lockjaw::builder_modules

#[builder_modules]

Annotates a struct that contains modules instances to be installed in a component with the builder_modules field. If a module contains fields, it cannot be auto generated and must be explicitly provided to COMPONENT.build()

The annotated struct will become the parameter for COMPONENT.build()

If a module does not contain any field, it can be auto generated by lockjaw, and can be listed in the modules field instead.

struct StringModule {
    string : String
}
#[module]
impl StringModule {
    #[provides]
    pub fn provide_string(&self) -> String {
        self.string.clone()
    }
}

#[builder_modules]
pub struct MyBuilderModules {
    module : crate::StringModule,
}
#[component(builder_modules : crate::MyBuilderModules)]
pub trait MyComponent {
    fn string(&self) -> String;
}

fn main() {
    let component = MyComponent::build(MyBuilderModules{
        module: StringModule{
            string: "foo".to_owned()
        }
    });
    
    assert_eq!("foo", component.string());
}
