Struct di::ScopedServiceProvider

pub struct ScopedServiceProvider { /* private fields */ }

Represents a scoped ServiceProvider.

Remarks

This struct has the exact same functionality as ServiceProvider. When a new instance is created, it also creates a new scope from the source ServiceProvider. The primary use case for this struct is to explicitly declare that a new scope should be created at the injection call site.
