Implementations

impl<C> VersionedXcm<C>

pub fn validate_xcm_nesting(&self) -> Result<(), ()>

Checks that the XCM is decodable with MAX_XCM_DECODE_DEPTH. Consequently, it also checks all decode implementations and limits, such as MAX_ITEMS_IN_ASSETS or MAX_INSTRUCTIONS_TO_DECODE.

Note that this uses the limit of the sender - not the receiver. It is a best effort.
