Struct runtime_injector::Module

pub struct Module { /* fields omitted */ }

A collection of providers that can be added all at once to an InjectorBuilder. Modules can be used to group together related services and configure the injector in pieces rather than all at once.

For creating a module easily via a domain specific language, see define_module!.
