Trait polkadot_service::AuthorityDiscoveryApi

pub trait AuthorityDiscoveryApi<Block>: Core<Block>where
    Block: Block,{
    fn authorities(
        &self,
        __runtime_api_at_param__: &BlockId<Block>
    ) -> Result<Vec<Public, Global>, ApiError> { ... }
    fn authorities_with_context(
        &self,
        __runtime_api_at_param__: &BlockId<Block>,
        context: ExecutionContext
    ) -> Result<Vec<Public, Global>, ApiError> { ... }
}

The authority discovery api.

This api is used by the client/authority-discovery module to retrieve identifiers of the current and next authority set.

Provided Methods

fn authorities(
    &self,
    __runtime_api_at_param__: &BlockId<Block>
) -> Result<Vec<Public, Global>, ApiError>

Retrieve authority identifiers of the current and next authority set.

fn authorities_with_context(
    &self,
    __runtime_api_at_param__: &BlockId<Block>,
    context: ExecutionContext
) -> Result<Vec<Public, Global>, ApiError>

Retrieve authority identifiers of the current and next authority set.
