}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.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
