Db!(MDBX, UserName);

// mdbx db flag list link Db!(MDBX, Tag, db::Flag::MDBX_DUPSORT);

fn main() -> Result<()> { unsafe { println!( "mdbx version https://github.com/erthink/libmdbx/releases/tag/v{}.{}.{}", mdbx::mdbxversion.major, mdbx::mdbxversion.minor, mdbx::mdbxversion.release ); } let t = std::thread::spawn(|| { let tx = &MDBX.w()?; let username = UserName & tx; username.set(&[3], &[4])?; dbg!("thread", username.get(&[2])?); dbg!("thread", user_name.get(&[3])?); Ok::<(), anyhow::Error>(()) });
