Cloneless Cow

Allows for the storage of a reference or owned instance of a generic type T.

Features

  • Convenient storage of a reference or owned instance, even (and especially) for types that do not implement Clone
  • Able to access the instance reference via .as_ref()

Limitations

  • Impossible to clone T directly out of the instance or get back the owned T
    • This feature of Cow is also a limitation of Cow which this crate does not suffer from, as Cow requires T to implement the Clone trait when you may only want access to a reference of T

No runtime deps
