Struct StateView 

Source 
pub struct StateView<'a, S: UserState> { /* private fields */ }
Expand description

Read-only view into engine state at a single point in time.

This type is used by:

  • observers
  • logging systems
  • extensions
  • external monitoring hooks

It provides safe immutable access without exposing ownership of the underlying State<S>.

Implementations§
