Module eso::eso

The Eso type and associated traits for advanced reference wrangling.

Beware that the flexibility of Eso comes at a rather high cost in ergonomics. The types are pretty complex and the where clauses are unwieldy. You should think twice before exposing anything related to it on the surface of your library.

Eso is meant as a building block for libraries that need the additional flexibility compared to the standard Cow type.

Modules
