* Reservable, Transferrable Fungible(s), plus adapters. * Repot into new dir * Imbalances for Fungibles * Repot and balanced fungible. * Clean up names and bridge-over Imbalanced. * Repot frame_support::trait. Finally. * Make build. * Docs * Good errors * Fix tests. Implement fungible::Inspect for Balances. * Implement additional traits for Balances. * Revert UI test "fixes" * Fix UI error * Fix UI test * More work on fungibles * Fixes * More work. * Update lock * Make fungible::reserved work for Balances * Introduce Freezer to Assets, ready for a reserve & locks pallet. Some renaming/refactoring. * Cleanup errors * Imbalances working with Assets * Test for freezer. * Grumbles * Grumbles * Fixes * Extra "side-car" data for a user's asset balance. * Fix * Fix test * Fixes * Line lengths * Comments * Update frame/assets/src/tests.rs Co-authored-by: Shawn Tabrizi <shawntabrizi@gmail.com> * Update frame/support/src/traits/tokens/fungibles.rs Co-authored-by: Shawn Tabrizi <shawntabrizi@gmail.com> * Update frame/assets/src/lib.rs Co-authored-by: Shawn Tabrizi <shawntabrizi@gmail.com> * Update frame/support/src/traits/tokens/fungible.rs Co-authored-by: Shawn Tabrizi <shawntabrizi@gmail.com> * Introduce `transfer_reserved` * Rename fungible Reserve -> Hold, add flag structs * Avoid the `melted` API - its too complex and gives little help * Repot Assets pallet Co-authored-by: Bastian Köcher <info@kchr.de> Co-authored-by: Shawn Tabrizi <shawntabrizi@gmail.com>
