Expand description

Error for the System pallet

Variants

`InvalidSpecName`

The name of specification does not match between the current runtime and the new runtime.

`SpecVersionNeedsToIncrease`

The specification version is not allowed to decrease between the current runtime and the new runtime.

`FailedToExtractRuntimeVersion`

Failed to extract the runtime version from the new runtime.

Either calling Core_version or decoding RuntimeVersion failed.

`NonDefaultComposite`

Suicide called when the account has non-default composite data.

`NonZeroRefCount`

There is a non-zero reference count preventing the account from being purged.

`CallFiltered`

The origin filter prevent the call to be dispatched.
