Trait StatefulStateMigratorV1 

pub trait StatefulStateMigratorV1: Send + Sync {
    // Required method
    fn migrate(
        &self,
        from_schema_version: u32,
        state: &[u8],
    ) -> Result<(u32, Vec<u8>), StatefulHandlerErrorV2>;
}

Host-provided migration hook. Migrations return a new state and never mutate the input, allowing the caller to preserve the previous-good copy.

Required Methods

fn migrate( &self, from_schema_version: u32, state: &[u8], ) -> Result<(u32, Vec<u8>), StatefulHandlerErrorV2>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
