Provided Methods§

source

fn on_runtime_upgrade() -> Weight

See Hooks::on_runtime_upgrade.

source

fn try_on_runtime_upgrade(checks: bool) -> Result<Weight, TryRuntimeError>

The expected and default behavior of this method is to handle executing pre_upgrade -> on_runtime_upgrade -> post_upgrade hooks for a migration.

Internally, the default implementation

Handles passing data from pre_upgrade to post_upgrade
Ensure storage is not modified in pre_upgrade and post_upgrade hooks.

Combining the pre_upgrade -> on_runtime_upgrade -> post_upgrade logic flow into a single method call is helpful for scenarios like testing a tuple of migrations, where the tuple contains order-dependent migrations.

source

fn pre_upgrade() -> Result<Vec<u8>, TryRuntimeError>

See Hooks::pre_upgrade.
