Struct frame_support::traits::tokens::fungible::LoneHoldConsideration
source · pub struct LoneHoldConsideration<A, Fx, Rx, D>(/* private fields */);
Expand description
Basic consideration method using a fungible
balance placed on hold as the cost exacted for the
footprint.
NOTE: This is an optimized implementation, which can only be used for systems where each
account has only a single active ticket associated with it since individual tickets do not
track the specific balance which is frozen. If you are uncertain then use FreezeConsideration
instead, since this works in all circumstances.

source§fn new(who: &A, footprint: Footprint) -> Result<Self, DispatchError>
fn new(who: &A, footprint: Footprint) -> Result<Self, DispatchError>
Create a ticket for the
new
footprint attributable to who
. This ticket must ultimately
be consumed through update
or drop
once the footprint changes or is removed.source§fn update(self, who: &A, footprint: Footprint) -> Result<Self, DispatchError>
fn update(self, who: &A, footprint: Footprint) -> Result<Self, DispatchError>
Optionally consume an old ticket and alter the footprint, enforcing the new cost to
who
and returning the new ticket (or an error if there was an issue). Read moresource§impl<A, Fx, Rx, D> Debug for LoneHoldConsideration<A, Fx, Rx, D>
