Trait sp_runtime::traits::BlockIdTo

pub trait BlockIdTo<Block: Block> {
    type Error: Debug;
    fn to_hash(
        &self, 
        block_id: &BlockId<Block>
    ) -> Result<Option<Block::Hash>, Self::Error>;
    fn to_number(
        &self, 
        block_id: &BlockId<Block>
    ) -> Result<Option<NumberFor<Block>>, Self::Error>;
}

Something that can convert a BlockId to a number or a hash.

Associated Types

type Error: Debug
