fn deposit_asset_with_surplus( what: AssetsInHolding, who: &Location, _context: Option<&XcmContext>, ) -> Result<Weight, (AssetsInHolding, XcmError)>

Deposits assets from holding to a beneficiary account via ERC20 transfer.

Note: This implementation only handles a single fungible asset at a time. The AssetsInHolding parameter is required by the TransactAsset trait, but callers should ensure only one asset is passed. If multiple assets are present, only the first fungible asset will be deposited and the rest will be silently ignored. The defensive_assert! helps catch misuse during development.

fn can_check_in( _origin: &Location, _what: &Asset, _context: &XcmContext, ) -> XcmResult

Ensure that check_in will do as expected.

fn check_in(_origin: &Location, _what: &Asset, _context: &XcmContext)

An asset has been teleported in from the given origin. This should do whatever housekeeping is needed.

fn can_check_out( _destination: &Location, _what: &Asset, _context: &XcmContext, ) -> XcmResult

Ensure that check_out will do as expected.

fn check_out(_destination: &Location, _what: &Asset, _context: &XcmContext)

An asset has been teleported out to the given destination. This should do whatever housekeeping is needed.

fn withdraw_asset_with_surplus( what: &Asset, who: &Location, _context: Option<&XcmContext>, ) -> Result<(AssetsInHolding, Weight), XcmError>

Withdraw assets returning surplus.

fn deposit_asset( what: AssetsInHolding, _who: &Location, _context: Option<&XcmContext>, ) -> Result<(), (AssetsInHolding, Error)>

Deposit the what asset in holding into the account of who.

fn withdraw_asset( _what: &Asset, _who: &Location, _maybe_context: Option<&XcmContext>, ) -> Result<AssetsInHolding, Error>

Withdraw the given asset from the consensus system.

fn internal_transfer_asset( _asset: &Asset, _from: &Location, _to: &Location, _context: &XcmContext, ) -> Result<Asset, Error>

Move an asset from one location in to another location.

fn internal_transfer_asset_with_surplus( asset: &Asset, from: &Location, to: &Location, context: &XcmContext, ) -> Result<(Asset, Weight), Error>

Identical to internal_transfer_asset but returning the surplus, if any.

fn transfer_asset( asset: &Asset, from: &Location, to: &Location, context: &XcmContext, ) -> Result<Asset, Error>

Move an asset from one location in to another location.

fn transfer_asset_with_surplus( asset: &Asset, from: &Location, to: &Location, context: &XcmContext, ) -> Result<(Asset, Weight), Error>

Identical to transfer_asset but returning the surplus, if any.

fn mint_asset( _what: &Asset, _context: &XcmContext, ) -> Result<AssetsInHolding, Error>

An asset has been minted and the imbalance returned into holding. This should do whatever housekeeping is needed.
