Overview

Package inventory contains the inventory manager. the inventory manager is one of the core pieces of the program which manages the currently available inventory.

"All" (committed & uncommitted inventory) is considered to be the current balance on all chains (so, you if you iterate through all erc-20's and call balanceOf()) that is the "All" inventory "Commitable" inventory is "All" inventory net of current commitments. Commitments occur when a user bridge request comes in and the relayer internally commits to filling it. This prevents overcommiting erc-20 balances.
