Expand description
The XCM executor.
Fields§
§holding: Assets
§origin: Option<MultiLocation>
§original_origin: MultiLocation
§trader: Config::Trader
§error: Option<(u32, XcmError)>
The most recent error result and instruction index into the fragment in which it occurred, if any.
total_surplus: u64
The surplus weight, defined as the amount by which max_weight
is
an over-estimate of the actual weight consumed. We do it this way to avoid needing the
execution engine to keep track of all instructions’ weights (it only needs to care about
the weight of dynamically determined instructions such as Transact
).
total_refunded: u64
§error_handler: Xcm<Config::Call>
§error_handler_weight: u64
§appendix: Xcm<Config::Call>
§appendix_weight: u64
Implementations§
source§impl<Config: Config> XcmExecutor<Config>
impl<Config: Config> XcmExecutor<Config>
pub fn new(origin: impl Into<MultiLocation>) -> Self
sourcepub fn execute(&mut self, xcm: Xcm<Config::Call>) -> Result<(), ExecutorError>
pub fn execute(&mut self, xcm: Xcm<Config::Call>) -> Result<(), ExecutorError>
Execute the XCM program fragment and report back the error and which instruction caused it,
or Ok
if there was no error.
sourcepub fn post_execute(self, xcm_weight: Weight) -> Outcome
pub fn post_execute(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.

weight_limit: u64
) -> Outcome
Execute some XCM
message
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. Read moreAuto Trait Implementations§
