Function cause_error

pub fn cause_error<T: Config>()

An example dispatchable that may throw a custom error.

It checks that the caller is a signed origin and reads the current value from the Something storage item. If a current value exists, it is incremented by 1 and then written back to storage.

Errors

The function will return an error under the following conditions:

• If no value has been set (Error::NoneValue)
• If incrementing the value in storage causes an arithmetic overflow (Error::StorageOverflow)

Warning: Doc-Only

This function is an automatically generated, and is doc-only, uncallable stub. See the real version in Pallet::cause_error.
