Required Methods§

Source

fn input_version(&self) -> u32

Input state version this migration expects to read (the underlying StateTransformer::input_version).

Source

fn output_version(&self) -> u32

Output state version this migration writes (the underlying StateTransformer::output_version).

Source

fn run(self)

Apply the migration, advancing the stored state version to Migrator::output_version. Consumes self; run only after the chain is validated.
