}Expand description
A convenient way to handle Context read access.
Rather than plumbing references to a context throughout your code, especially when you are implementing derive macros that rely on this crate, it can be more convenient to use this abstraction of read-only access to a context.
In most hand-written code, it is simplest to use a shared reference to a context as an Accessor.
