Trait ParachainRegistrar 

pub trait ParachainRegistrar {
    type AccountId;

    // Required methods
    fn check_onboarding(head_len: u32, code_len: u32) -> Result<(), ()>;
    fn is_registered(para_id: ParaId) -> bool;
    fn register(
        manager: Self::AccountId,
        para_id: ParaId,
        genesis_head: Vec<u8>,
        validation_code: Vec<u8>,
    ) -> DispatchResult;
}

The parachain registry, as pallet-registrar-relay needs to see it.

Implemented by whichever pallet owns parachain registration, typically paras_registrar on the relay chain. Lives here so neither side of the protocol has to depend on the other.

Required Associated Types

type AccountId

The account id used to identify a registration’s manager.

Required Methods

fn check_onboarding(head_len: u32, code_len: u32) -> Result<(), ()>

Whether head data and code of these sizes could be onboarded right now.

Checked against the relay chain’s live configuration so a doomed request can be rejected before the user goes and uploads megabytes of code.

fn is_registered(para_id: ParaId) -> bool

Whether the relay chain already knows this para id.

fn register( manager: Self::AccountId, para_id: ParaId, genesis_head: Vec<u8>, validation_code: Vec<u8>, ) -> DispatchResult

Onboard para_id under manager.

No deposit is taken: the manager’s funds are held on the chain running pallet-registrar-para.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
