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Withdraw could not happen since the amount to be withdrawn is less than the total funds in the account.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

Implementations

Convert the type into a Result with DispatchError as the error or the additional Balance by which the account will be reduced.
