Trait staging_xcm_builder::ExecuteController

pub trait ExecuteController<Origin, RuntimeCall> {
    type WeightInfo: ExecuteControllerWeightInfo;

    // Required method
    fn execute(
        origin: Origin,
        message: Box<VersionedXcm<RuntimeCall>>,
        max_weight: Weight,
    ) -> Result<Weight, DispatchErrorWithPostInfo>;
}

Execute an XCM locally, for a given origin.

An implementation of that trait will handle the low-level details of the execution, such as:

• Validating and Converting the origin to a Location.
• Handling versioning.
• Calling the internal executor, which implements ExecuteXcm.

Required Associated Types

type WeightInfo: ExecuteControllerWeightInfo

Weight information for ExecuteController functions.

Required Methods

fn execute( origin: Origin, message: Box<VersionedXcm<RuntimeCall>>, max_weight: Weight, ) -> Result<Weight, DispatchErrorWithPostInfo>

Attempt to execute an XCM locally, returns Ok with the weight consumed if the execution complete successfully, Err otherwise.

Parameters

• origin: the origin of the call.
• message: the XCM program to be executed.
• max_weight: the maximum weight that can be consumed by the execution.

Object Safety

This trait is not object safe.
