Struct pallet_treasury::migration::cleanup_proposals::Migration

source · 
pub struct Migration<T, I, UnreserveWeight>(/* private fields */);
Expand description

Migration to cleanup unapproved proposals to return the bonds back to the proposers. Proposals can no longer be created and the Proposal storage item will be removed in the future.

UnreserveWeight returns Weight of unreserve_balance operation which is perfomed during this migration.
