Pfx.invert

You're seeing just the function invert, go back to Pfx module for more information.

Inverts a prefix, bit by bit, same as Pfx.bnot/1.

This function inverts all bits in the prefix by simply calling Pfx.bnot/1, whose name is somewhat obscure. See Pfx.bnot/1 for documentation.

Note: using Pfx.bnot/1 directly, actually saves a function call.
