Runtime Version for Handles

• MUST be incremented if anything changes
• Also update in js/api-augment
• See: https://paritytech.github.io/polkadot/doc/polkadot_primitives/runtime_api/index.html Runtime APIs for Handles

Provided Methods

fn get_handle_for_msa( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, msa_id: MessageSourceId ) -> Result<Option<HandleResponse>, ApiError>

Retrieve handle for a particular msa

fn get_next_suffixes( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, base_handle: BaseHandle, count: u16 ) -> Result<PresumptiveSuffixesResponse, ApiError>

Retrieve the next n suffixes for a given handle

fn get_msa_for_handle( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, display_handle: DisplayHandle ) -> Result<Option<MessageSourceId>, ApiError>

Retrieve msa for a particular handle

fn validate_handle( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, base_handle: BaseHandle ) -> Result<bool, ApiError>

Check if a handle is valid
