Struct Provider

pub struct Provider<'a, T> { /* private fields */ }

Creates a binding on demand

T will be created each time Provider.get() is called, allowing multiple instances to be created.

This also prevents creating T immediately when constructing an object that depends on T, which allows lazy initialization and can break cyclic dependency.

WARNING: calling Provider.get() in a constructor can lead to stackoverflow, and is best avoided.

If only a single cached instance is needed, consider using Lazy<T>(Lazy) instead.
