Attribute Macro lockjaw::module_attributes::binds_option_of

#[binds_option_of]

Declares an optional binding.

If #[binds_option_of] pub fn option_foo()->Option<Foo> is declared, injecting Option<Foo> will result in Some(Foo) if Foo is bound elsewhere. Otherwise it results in None.

Typically this is used if an optional feature is provided by another module which may not be included in the component.
