Implementations§

Source§

impl BlockchainDb

Source

pub fn new(meta: BlockchainDbMeta, cache_path: Option<PathBuf>) -> Self

Creates a new instance of the BlockchainDb.

If a cache_path is provided it attempts to load a previously stored JsonBlockCacheData and will try to use the cached entries it holds.

This will return a new and empty MemDb if

  • cache_path is None
  • the file the cache_path points to, does not exist
  • the file contains malformed data, or if it couldn’t be read
  • the provided meta differs from BlockchainDbMeta that’s stored on disk
Source

pub fn new_skip_check( meta: BlockchainDbMeta, cache_path: Option<PathBuf>, ) -> Self

Creates a new instance of the BlockchainDb and skips check when comparing meta This is useful for offline-start mode when we don’t want to fetch metadata of block.

if a cache_path is provided it attempts to load a previously stored JsonBlockCacheData and will try to use the cached entries it holds.

This will return a new and empty MemDb if

  • cache_path is None
  • the file the cache_path points to, does not exist
  • the file contains malformed data, or if it couldn’t be read
  • the provided meta differs from BlockchainDbMeta that’s stored on disk
