Struct RequestExtensions 

pub struct RequestExtensions { /* private fields */ }

A neutral type-map for per-request execution metadata.

The library treats this as an opaque slot. It passes extensions to BudgetManager methods so implementors can extract identity, routing keys, or any other metadata they need. It also passes extensions to EventHandler so handlers can inspect them during streaming.

The library treats entries in RequestExtensions as opaque. All entries are user-defined.
