pub struct Imbalance<B: Balance, OnDrop: HandleImbalanceDrop<B>, OppositeOnDrop: HandleImbalanceDrop<B>> { /* private fields */ }
Expand description
An imbalance in the system, representing a divergence of recorded token supply from the sum of
the balances of all accounts. This is must_use
in order to ensure it gets handled (placing
into an account, settling from an account or altering the supply).
Importantly, it has a special Drop
impl, and cannot be created outside of this module.
