Trait Implementations§

source§

impl<A, F> Pay for PayFromAccount<F, A>
where A: TypedGet, F: Mutate<A::Type>, A::Type: Eq,

§

type Balance = <F as Inspect<<A as TypedGet>::Type>>::Balance

The type by which we measure units of the currency in which we make payments.
§

type Beneficiary = <A as TypedGet>::Type

The type by which we identify the beneficiaries to whom a payment may be made.
§

type AssetKind = ()

The type for the kinds of asset that are going to be paid. Read more
§

type Id = ()

An identifier given to an individual payment.
§

type Error = DispatchError

An error which could be returned by the Pay type
source§

fn pay( who: &Self::Beneficiary, _: Self::AssetKind, amount: Self::Balance, ) -> Result<Self::Id, Self::Error>

Make a payment and return an identifier for later evaluation of success in some off-chain mechanism (likely an event, but possibly not on this chain).
source§

fn check_payment(_: ()) -> PaymentStatus

Check how a payment has proceeded. id must have been previously returned by pay for the result of this call to be meaningful. Once this returns anything other than InProgress for some id it must return Unknown rather than the actual result value.
source§

fn ensure_successful( _: &Self::Beneficiary, _: Self::AssetKind, amount: Self::Balance, )

Ensure that a call to pay with the given parameters will be successful if done immediately after this call. Used in benchmarking code.
source§

fn ensure_concluded(_: Self::Id)

Ensure that a call to check_payment with the given parameters will return either Success or Failure.
