Kinda.Testing.NIFUpgrade (kinda v0.12.0)

Copy Markdown View Source

Test support for loading a second copy of a NIF into an existing module.

The copied library keeps the same native entry name; the distinct path only gives the dynamic loader a second image to pass through the NIF upgrade callback. Use the separate kinda_sandbox package when the entry name itself must differ.
