Trait StateMigrationApiServer

pub trait StateMigrationApiServer<BlockHash>:
    Sized
    + Send
    + Sync
    + 'static {
    // Required method
    fn call(
        &self,
        ext: &Extensions,
        at: Option<BlockHash>,
    ) -> RpcResult<MigrationStatusResult>;

    // Provided method
    fn into_rpc(self) -> RpcModule<Self>
       where BlockHash: Send + Sync + 'static + DeserializeOwned { ... }
}

Server trait implementation for the StateMigrationApi RPC API.

Required Methods

fn call( &self, ext: &Extensions, at: Option<BlockHash>, ) -> RpcResult<MigrationStatusResult>

Check current migration state.

This call is performed locally without submitting any transactions. Thus executing this won’t change any state. Nonetheless it is a VERY costly call that should be only exposed to trusted peers.

Provided Methods

fn into_rpc(self) -> RpcModule<Self>

where BlockHash: Send + Sync + 'static + DeserializeOwned,

Collects all the methods and subscriptions defined in the trait and adds them into a single RpcModule.

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.
