Expand description

One of a number of consequences of withdrawing a fungible from an account.

Variants

`NoFunds`

Withdraw could not happen since the amount to be withdrawn is less than the total funds in the account.

`WouldDie`

The withdraw would mean the account dying when it needs to exist (usually because it is a provider and there are consumer references on it).

`UnknownAsset`

The asset is unknown. Usually because an AssetId has been presented which doesn’t exist on the system.

`Underflow`

There has been an underflow in the system. This is indicative of a corrupt state and likely unrecoverable.

`Overflow`

There has been an overflow in the system. This is indicative of a corrupt state and likely unrecoverable.

`Frozen`

Not enough of the funds in the account are unavailable for withdrawal.

`ReducedToZero(Balance)`

Account balance would reduce to zero, potentially destroying it. The parameter is the amount of balance which is destroyed.

`Success`

Account continued in existence.
