Expand description

Parachain registration API.

Required Associated Types§

source

type AccountId

The account ID type that encodes a parachain manager ID.

Required Methods§

source

fn manager_of(id: ParaId) -> Option<Self::AccountId>

Report the manager (permissioned owner) of a parachain, if there is one.

source

fn parachains() -> Vec<ParaId>

All lease holding parachains. Ordered ascending by ParaId. On-demand parachains are not included.

source

fn is_parathread(id: ParaId) -> bool

Return if a ParaId is a Parathread (on-demand parachain).

source

fn apply_lock(id: ParaId)

Apply a lock to the para registration so that it cannot be modified by the manager directly. Instead the para must use its sovereign governance or the governance of the relay chain.
