Trait BlockBodyIndicesProvider

pub trait BlockBodyIndicesProvider: Send + Sync {
    // Required methods
    fn block_body_indices(
        &self,
        num: u64,
    ) -> ProviderResult<Option<StoredBlockBodyIndices>>;
    fn block_body_indices_range(
        &self,
        range: RangeInclusive<BlockNumber>,
    ) -> ProviderResult<Vec<StoredBlockBodyIndices>>;
}

Client trait for fetching block body indices related data.

Required Methods

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

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<BlockNumber>, ) -> ProviderResult<Vec<StoredBlockBodyIndices>>

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