Trait kilt_support::traits::VersionMigratorTrait

pub trait VersionMigratorTrait<T>: Sized {
    // Required methods
    fn pre_migrate(&self) -> Result<(), &'static str>;
    fn migrate(&self) -> Weight;
    fn post_migrate(&self) -> Result<(), &'static str>;
}

A trait that allows version migrators to access the underlying pallet’s context, e.g., its Config trait.

In this way, the migrator can access the pallet’s storage and the pallet’s types directly.

Required Methods

fn pre_migrate(&self) -> Result<(), &'static str>

fn migrate(&self) -> Weight

fn post_migrate(&self) -> Result<(), &'static str>
