Struct frame_support::traits::NoStorageVersionSet

source · 
pub struct NoStorageVersionSet;
Expand description

Special marker struct if no storage version is set for a pallet.

If you (the reader) end up here, it probably means that you tried to compare GetStorageVersion::on_chain_storage_version against GetStorageVersion::current_storage_version. This basically means that the storage_version is missing in the pallet where the mentioned functions are being called.
