Struct tetcore_test_client::Backend [−][src]
Disk backend.
Disk backend keeps data in a key-value store. In archive mode, trie nodes are kept from all blocks. Otherwise, trie nodes are kept only from some recent blocks.
Implementations
impl<Block> Backend<Block> where
Block: Block, [src]
Block: Block,
pub fn new(
config: DatabaseSettings,
canonicalization_delay: u64
) -> Result<Backend<Block>, Error>[src]
config: DatabaseSettings,
canonicalization_delay: u64
) -> Result<Backend<Block>, Error>
Create a new instance of database backend.
The pruning window is how old a block must be before the state is pruned.
pub fn new_test(keep_blocks: u32, canonicalization_delay: u64) -> Backend<Block>[src]
Create new memory-backed client backend for tests.
