Provided methods

fn is_inherent_required(
    _: &InherentData
) -> Result<Option<Self::Error>, Self::Error>[src]

If Some, indicates that an inherent is required. Check will return the inner error if no inherent is found. If Err, indicates that the check failed and further operations should be aborted.

fn check_inherent(_: &Self::Call, _: &InherentData) -> Result<(), Self::Error>[src]

Check the given inherent if it is valid. Checking the inherent is optional and can be omitted.
