Expand description

Interface used to store and retrieve Ethereum mappings from the database. To store IPLD blocks, use the BlockStore trait.

Required Methods§

Source

fn read_bin(&self, key: &EthHash) -> Result<Option<Vec<u8>>>

Reads binary field from the EthMappings store. This should be used for non-serializable data. For serializable data, use EthMappingsStoreExt::read_obj.

Source

fn write_bin(&self, key: &EthHash, value: &[u8]) -> Result<()>

Writes binary field to the EthMappings store. This should be used for non-serializable data. For serializable data, use EthMappingsStoreExt::write_obj.
