Function obj_txn_commit 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn obj_txn_commit(
    txn: *mut obj_write_txn_t,
) -> obj_error_t

Commit a write transaction. Consumes the handle — the C caller MUST NOT touch txn again after this returns.

Safety

txn must be a non-null handle returned by obj_txn_begin_write and not yet committed / rolled back.
