Trait BlockBodyIndicesProvider 

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

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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
