-/// Context API
-///
-/// The context API provides a mechanism for components to borrow state from other components higher in the tree.
-/// By combining the Context API and the Subscription API, we can craft ergonomic global state management systems.
-///
-/// This API is inherently dangerous because we could easily cause UB by allowing &T and &mut T to exist at the same time.
-/// To prevent this, we expose the RemoteState<T> and RemoteLock<T> types which act as a form of reverse borrowing.
-/// This is very similar to RwLock, except that RemoteState is copy-able. Unlike RwLock, derefing RemoteState can
-/// cause panics if the pointer is null. In essence, we sacrifice the panic protection for ergonomics, but arrive at
-/// a similar end result.
-///
-/// Instead of placing the onus on the receiver of the data to use it properly, we wrap the source object in a
-/// "shield" where gaining &mut access can only be done if no active StateGuards are open. This would fail and indicate
-/// a failure of implementation.

-/// # SAFETY ALERT
-///
-/// The underlying context mechanism relies on mutating &mut T while &T is held by components in the tree.
-/// By definition, this is UB. Therefore, implementing use_context should be done with upmost care to invalidate and
-/// prevent any code where &T is still being held after &mut T has been taken and T has been mutated.
-///
-/// While mutating &mut T while &T is captured by listeners, we can do any of:
-///     1) Prevent those listeners from being called and avoid "producing" UB values
-///     2) Delete instances of closures where &T is captured before &mut T is taken
-///     3) Make clones of T to preserve the original &T.
-///     4) Disable any &T remotely (like RwLock, RefCell, etc)
-///
-/// To guarantee safe usage of state management solutions, we provide Dioxus-Reducer and Dioxus-Dataflow built on the
-/// SafeContext API. This should provide as an example of how to implement context safely for 3rd party state management.
-///
-/// It's important to recognize that while safety is a top concern for Dioxus, ergonomics do take prescendence.
-/// Contrasting with the JS ecosystem, Rust is faster, but actually "less safe". JS is, by default, a "safe" language.
-/// However, it does not protect you against data races: the primary concern for 3rd party implementers of Context.
-///
-/// We guarantee that any &T will remain consistent throughout the life of the Virtual Dom and that
-/// &T is owned by components owned by the VirtualDom. Therefore, it is impossible for &T to:
-/// - be dangling or unaligned
-/// - produce an invalid value
-/// - produce uninitialized memory
-///
-/// The only UB that is left to the implementer to prevent are Data Races.
-///
-/// Here's a strategy that is UB:
-/// 1. &T is handed out via use_context
-/// 2. an event is reduced against the state
-/// 3. An &mut T is taken
-/// 4. &mut T is mutated.
-///
-/// Now, any closures that caputed &T are subject to a data race where they might have skipped checks and UB
-/// *will* affect the program.
-///
-/// Here's a strategy that's not UB (implemented by SafeContext):
-/// 1. ContextGuard<T> is handed out via use_context.
-/// 2. An event is reduced against the state.
-/// 3. The state is cloned.
-/// 4. All subfield selectors are evaluated and then diffed with the original.
-/// 5. Fields that have changed have their ContextGuard poisoned, revoking their ability to take &T.a.
-/// 6. The affected fields of Context are mutated.
