Expand description
Type of XCM message executor.
Required Associated Types§
Required Methods§
fn prepare(message: Xcm<Call>) -> Result<Self::Prepared, Xcm<Call>>
fn execute( origin: impl Into<MultiLocation>, pre: Self::Prepared, id: &mut XcmHash, weight_credit: Weight, ) -> Outcome
sourcefn charge_fees(location: impl Into<MultiLocation>, fees: MultiAssets) -> Result
fn charge_fees(location: impl Into<MultiLocation>, fees: MultiAssets) -> Result
Deduct some fees
to the sovereign account of the given location
and place them as per
the convention for fees.
Provided Methods§
fn prepare_and_execute( origin: impl Into<MultiLocation>, message: Xcm<Call>, id: &mut XcmHash, weight_limit: Weight, weight_credit: Weight, ) -> Outcome
sourcefn execute_xcm(
origin: impl Into<MultiLocation>,
message: Xcm<Call>,
hash: XcmHash,
weight_limit: Weight,
) -> Outcome
fn execute_xcm( origin: impl Into<MultiLocation>, message: Xcm<Call>, hash: XcmHash, weight_limit: Weight, ) -> Outcome
Execute some XCM message
with the message hash
from origin
using no more than
weight_limit
weight.
The weight limit is a basic hard-limit and the implementation may place further restrictions or requirements on weight and other aspects.
sourcefn execute_xcm_in_credit(
origin: impl Into<MultiLocation>,
message: Xcm<Call>,
hash: XcmHash,
weight_limit: Weight,
weight_credit: Weight,
) -> Outcome
fn execute_xcm_in_credit( origin: impl Into<MultiLocation>, message: Xcm<Call>, hash: XcmHash, weight_limit: Weight, weight_credit: Weight, ) -> Outcome
Execute some XCM message
with the message hash
from origin
using no more than
weight_limit
weight.
Some amount of weight_credit
may be provided which, depending on the implementation, may
allow execution without associated payment.
