Function sqlite_loadable::prelude::register_entrypoint

pub fn register_entrypoint<F>(
    db: *mut sqlite3,
    _pz_err_msg: *mut *mut c_char,
    p_api: *mut sqlite3_api_routines,
    callback: F
) -> c_uintwhere
    F: Fn(*mut sqlite3) -> Result<()>,

Low-level wrapper around a typical entrypoint to a SQLite extension. You shouldn’t have to use this directly - the sqlite_entrypoint macro will do this for you.
