[−][src]Function rusqlite::trace::config_log

pub unsafe fn config_log(callback: Option<fn(_: c_int, _: &str)>) -> Result<()>

Set up the process-wide SQLite error logging callback. This function is marked unsafe for two reasons:

  • The function is not threadsafe. No other SQLite calls may be made while config_log is running, and multiple threads may not call config_log simultaneously.
  • The provided callback itself function has two requirements:
    • It must not invoke any SQLite calls.
    • It must be threadsafe if SQLite is used in a multithreaded way.
