Re-export the API for backward compatibility. Server trait implementation for the OffchainApi RPC API.

Required Methods

fn set_local_storage( &self, ext: &Extensions, kind: StorageKind, key: Bytes, value: Bytes, ) -> Result<(), Error>

Set offchain local storage under given key and prefix.

fn clear_local_storage( &self, ext: &Extensions, kind: StorageKind, key: Bytes, ) -> Result<(), Error>

Clear offchain local storage under given key and prefix.

fn get_local_storage( &self, ext: &Extensions, kind: StorageKind, key: Bytes, ) -> Result<Option<Bytes>, Error>

Get offchain local storage under given key and prefix.

Provided Methods

fn into_rpc(self) -> RpcModule<Self>

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.
