Crate reth_era_utils 

Moves block history between ERA files (reth_era) and node storage (reth_storage_api).

Each ERA format plugs into a shared pipeline through a per-format seam (EraBlockReader).

EraBlockReader for .era1 files.

Ere

EraBlockReader for .ere/.erae files.

ExportBlock

One block’s data, gathered by export and handed to an EraBlockWriter.

calculate_td_by_number

Calculates the total difficulty for a given block number by summing the difficulty of all blocks from genesis to the given block.

export

Fetches block history from provider and writes it to ERA files in the W format, chunked by ExportConfig::max_blocks_per_file.

import

Imports blocks from downloader, decoding each file with the EraBlockReader S.
