Expand description

Client trait for fetching block hashes by number.

Required Methods§

fn block_hash( &self, number: u64, ) -> Result<Option<FixedBytes<32>>, ProviderError>

Get the hash of the block with the given number. Returns None if no block with this number exists.

fn canonical_hashes_range( &self, start: u64, end: u64, ) -> Result<Vec<FixedBytes<32>>, ProviderError>

Get headers in range of block hashes or numbers

Returns the available hashes of that range.

Note: The range is start..end, so the expected result is [start..end)

Provided Methods§

fn convert_block_hash( &self, hash_or_number: HashOrNumber, ) -> Result<Option<FixedBytes<32>>, ProviderError>

Get the hash of the block with the given number. Returns None if no block with this number exists.
