//! Implement synchronous views of circuit internals.

/// A view of a circuit hop's internals, usable in a synchronous callback.
//
// TODO: I would rather have this type have a mutable reference to the reactor itself,
// rather than just an immutable reference to a piece of it.
// But that creates borrow-checker problems, so instead for now,
// we only hold references to the pieces we need.
// If we need to hold more info in the future,
// we'll need to decide whether to create additional types for the more complex variants,
// or whether to try to stuff everything inside this type.
