Struct SqliteHeaderDb 

pub struct SqliteHeaderDb { /* private fields */ }

Header storage implementation with SQL Lite.

Implementations

impl SqliteHeaderDb

pub fn new( network: Network, path: Option<PathBuf>, ) -> Result<Self, SqlInitializationError>

Create a new SqliteHeaderDb with an optional file path. If no path is provided, the file will be stored in a data subdirectory where the program is ran.
