Expand description
Trait to determine whether the execution engine should actually execute a given XCM.
Can be amalgamated into a tuple to have multiple trials. If any of the tuple elements returns
Ok(())
, the execution stops. Else, Err(_)
is returned if all elements reject the message.
Required Methods§
sourcefn should_execute<RuntimeCall>(
origin: &Location,
instructions: &mut [Instruction<RuntimeCall>],
max_weight: Weight,
properties: &mut Properties,
) -> Result<(), ProcessMessageError>
fn should_execute<RuntimeCall>( origin: &Location, instructions: &mut [Instruction<RuntimeCall>], max_weight: Weight, properties: &mut Properties, ) -> Result<(), ProcessMessageError>
Returns Ok(())
if the given message
may be executed.
origin
: The origin (sender) of the message.instructions
: The message itself.max_weight
: The (possibly over-) estimation of the weight of execution of the message.properties
: Various pre-established properties of the message which may be mutated by this API.
