Function libduckdb_sys::duckdb_appender_flush

pub unsafe extern "C" fn duckdb_appender_flush(
    appender: duckdb_appender
) -> duckdb_state

Flush the appender to the table, forcing the cache of the appender to be cleared and the data to be appended to the base table.

This should generally not be used unless you know what you are doing. Instead, call duckdb_appender_destroy when you are done with the appender.

appender: The appender to flush. returns: DuckDBSuccess on success or DuckDBError on failure.
