Expand description
Interface used to store and retrieve Ethereum mappings from the database.
To store IPLD blocks, use the BlockStore
trait.
Required Methods§
sourcefn read_bin(&self, key: &EthHash) -> Result<Option<Vec<u8>>>
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
.
sourcefn write_bin(&self, key: &EthHash, value: &[u8]) -> Result<()>
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
.
