Implementations

impl<T> Pallet<T>

where T: Config,

pub fn force_lease( origin: <T as Config>::RuntimeOrigin, para: Id, leaser: <T as Config>::AccountId, amount: <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance, period_begin: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, period_count: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, ) -> Result<(), DispatchError>

Just a connect into the lease_out call, in case Root wants to force some lease to happen independently of any other on-chain mechanism to use it.

The dispatch origin for this call must match T::ForceOrigin.

pub fn clear_all_leases( origin: <T as Config>::RuntimeOrigin, para: Id, ) -> Result<(), DispatchError>

Clear all leases for a Para Id, refunding any deposits back to the original owners.

The dispatch origin for this call must match T::ForceOrigin.

pub fn trigger_onboard( origin: <T as Config>::RuntimeOrigin, para: Id, ) -> Result<(), DispatchError>

Try to onboard a parachain that has a lease for the current lease period.

This function can be useful if there was some state issue with a para that should have onboarded, but was unable to. As long as they have a lease period, we can let them onboard from here.

Origin must be signed, but can be called by anyone.
