Trait UncheckedOnRuntimeUpgrade

pub trait UncheckedOnRuntimeUpgrade {
    // Provided method
    fn on_runtime_upgrade() -> Weight { ... }
}

This trait is intended for use within VersionedMigration to execute storage migrations without automatic version checks. Implementations should ensure migration logic is safe and idempotent.

Provided Methods

fn on_runtime_upgrade() -> Weight

Called within VersionedMigration to execute the actual migration. It is also expected that no version checks are performed within this function.

See also Hooks::on_runtime_upgrade.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
