Attribute Macro oasis_runtime_sdk::migration

#[migration]

A helper attribute for #[sdk_derive(...)]. It doesn’t do anything on its own; it only marks functions that represent a module state migration.

The permitted forms are:

• #[migration(init)]: Marks the initial (genesis) migration.
• #[migration(from = v)]: Marks a migration from version v to v+1, where v is a non-negative integer.
