Struct XcmExecutor 

pub struct XcmExecutor<Config>
where
    Config: Config,
{ /* private fields */ }

The XCM executor.

Implementations

impl<Config> XcmExecutor<Config>

where Config: Config,

pub fn new( origin: impl Into<Location>, message_id: [u8; 32], ) -> XcmExecutor<Config>

pub fn post_process(self, xcm_weight: Weight) -> Outcome

Execute any final operations after having executed the XCM message. This includes refunding surplus weight, trapping extra holding funds, and returning any errors during execution.

Trait Implementations

impl<Config> ExecuteXcm<<Config as Config>::RuntimeCall> for XcmExecutor<Config>

where Config: Config,

type Prepared = WeighedMessage<<Config as Config>::RuntimeCall>

fn prepare( message: Xcm<<Config as Config>::RuntimeCall>, weight_limit: Weight, ) -> Result<<XcmExecutor<Config> as ExecuteXcm<<Config as Config>::RuntimeCall>>::Prepared, InstructionError>

If it fails, returns the index of the problematic instruction.

fn execute( origin: impl Into<Location>, _: WeighedMessage<<Config as Config>::RuntimeCall>, id: &mut [u8; 32], weight_credit: Weight, ) -> Outcome

fn charge_fees(origin: impl Into<Location>, fees: Assets) -> Result<(), Error>

Deduct some fees to the sovereign account of the given location and place them as per the convention for fees.

fn prepare_and_execute( origin: impl Into<Location>, message: Xcm<Call>, id: &mut [u8; 32], weight_limit: Weight, weight_credit: Weight, ) -> Outcome

impl<Config> FeeManager for XcmExecutor<Config>

where Config: Config,

fn is_waived(origin: Option<&Location>, r: FeeReason) -> bool

Determine if a fee should be waived.

fn handle_fee(fee: Assets, context: Option<&XcmContext>, r: FeeReason)

Do something with the fee which has been paid. Doing nothing here silently burns the fees.

impl<Config> XcmAssetTransfers for XcmExecutor<Config>

where Config: Config,

type IsReserve = <Config as Config>::IsReserve

Combinations of (Asset, Location) pairs which we trust as reserves. Meaning reserve-based-transfers are to be used for assets matching this filter.

type IsTeleporter = <Config as Config>::IsTeleporter

Combinations of (Asset, Location) pairs which we trust as teleporters. Meaning teleports are to be used for assets matching this filter.

type AssetTransactor = <Config as Config>::AssetTransactor

How to withdraw and deposit an asset.

fn determine_for(asset: &Asset, dest: &Location) -> Result<TransferType, Error>

Determine transfer type to be used for transferring asset from local chain to dest.
