Trait BlockBodyIndicesProvider

pub trait BlockBodyIndicesProvider: Send + Sync {
    // Required methods
    fn block_body_indices(
        &self,
        num: u64,
    ) -> Result<Option<StoredBlockBodyIndices>, ProviderError>;

    ) -> Result<Vec<StoredBlockBodyIndices>, ProviderError>;
}

Available on crate feature provider only.

Client trait for fetching block body indices related data.

Required Methods

fn block_body_indices( &self, num: u64, ) -> Result<Option<StoredBlockBodyIndices>, ProviderError>

Returns the block body indices with matching number from database.

Returns None if block is not found.

fn block_body_indices_range( &self, range: RangeInclusive<u64>, ) -> Result<Vec<StoredBlockBodyIndices>, ProviderError>

Returns the block body indices within the requested range matching number from storage.
