Implementations§

source§

impl<T: Config> Pallet<T>

source

pub fn add_transfer_allowance( origin: OriginFor<T>, currency_id: T::CurrencyId, receiver: T::Location ) -> DispatchResult

Adds a transfer allowance for a sending Account/Currency. Allowance either starts at the current block + the delay set for the account, if a delay is present. or block 0 if no delay is present. Important! Account/Currency sets with an allowance set are restricted to just the allowances added for the account - to have unrestricted transfers allowed for the sending Account and Currency, no allowances should be present.

Running this for an existing allowance generates a new allowance based on the current delay, or lack thereof

source

pub fn remove_transfer_allowance( origin: OriginFor<T>, currency_id: T::CurrencyId, receiver: T::Location ) -> DispatchResult

Restricts a transfer allowance for a sending account/currency/receiver location to:

  • either the current block + delay if a delay is set
  • or the current block if no delay is set
source

pub fn purge_transfer_allowance( origin: OriginFor<T>, currency_id: T::CurrencyId, receiver: T::Location ) -> DispatchResult

Removes a transfer allowance for a sending account/currency and receiving location Decrements or removes the sending account/currency count.

source

pub fn add_allowance_delay( origin: OriginFor<T>, currency_id: T::CurrencyId, delay: BlockNumberFor<T> ) -> DispatchResult

Adds an account/currency delay Calling on an account/currency with an existing delay will fail. To update a delay the delay has to be set to future modifiable. then an update delay extrinsic called

source

pub fn update_allowance_delay( origin: OriginFor<T>, currency_id: T::CurrencyId, delay: BlockNumberFor<T> ) -> DispatchResult

Updates an allowance delay, only callable if the delay has been set to allow future modifications and the delay modifiable_at block has been passed.

source

pub fn toggle_allowance_delay_once_future_modifiable( origin: OriginFor<T>, currency_id: T::CurrencyId ) -> DispatchResult

This allows the delay value to be modified after the current delay has passed since the current block Or sets the delay value to be not modifiable iff modifiable at has already passed

source

pub fn purge_allowance_delay( origin: OriginFor<T>, currency_id: T::CurrencyId ) -> DispatchResult

Removes an existing sending account/currency delay

source§

impl<T: Config> Pallet<T>

source

pub fn increment_or_create_allowance_count( account_id: &T::AccountId, currency_id: &T::CurrencyId ) -> DispatchResult

Increments number of allowances present for a sending account/currency set. If no allowances set, an entry with 1 added, if entry already present, it is then incremented.

source

pub fn decrement_or_remove_allowance_count( account_id: &T::AccountId, currency_id: &T::CurrencyId ) -> DispatchResult

Decrements the number of allowances tracked for a sending account/currency set. If the allowance count is currently 1, then it removes the entry If greater than 1, then decremented. If no entry present, NoAllowancesSet error returned.

source§

source§

This checks to see if a transfer from an account and currency should be allowed to a given location. If there are no allowances defined for the sending account and currency, then the transfer is allowed. If there is an allowance for the sending account and currency, but the destination does not have an allowance added then the transfer is not allowed. If there is an allowance for the sending account and currency, and there’s an allowance present: then we check whether the current block is between the allowed_at and blocked_at blocks in the allowance.
