Goodbye, Scope

This long-awaited release changes the nature of the reactive system by removing the entire concept of explicit Scope and the ubiquitous cx variable.

The primary impetus behind this change is that it increases the correctness of the behavior of the reactive system, and fixes several persistent issues.

From 0.0 to 0.4, Leptos allocated signals in a dedicated Scope, which was ubiquitous in APIs. This had several drawbacks

  1. Ergonomics: It was annoying additional boilerplate to pass around.
  2. Trait implementations: Needing an additional Scope argument on many functions prevented us from implementing many traits that could not take an additional argument on signals, like From, Serialize/Deserialize.
  3. Correctness: Two characteristics made this system somewhat broken
  • The Scope was stored in a variable that was passed around, meaning that the “wrong” scope could be passed into functions (most frequently Resource::read()). If, for example, a derived signal or memo read from a resource in the component body, and was called under a Suspense lower in the tree, the Scope used would be from the parent component, not the Suspense. This was just wrong, but involved wrapping the function in another closure to pass in the correct Scope.
  • It was relatively easy to create situations, that could leak memory unless child Scopes were manually created and disposed, or in which on_cleanup was never called. (See #802 and #918 for more background.)
