MongoDB Go Driver Low-Level Driver Library

The packages within this library allow users to build applications using a low-level driver interface. Knowledge of the internals of a MongoDB driver are assumed, so this library contains advanced features. The aim of this library is to provide an easy to use, high performance implementation of a low-level driver.

This Library's API is experimental and subject to change. Packages may be changed or removed without notice. These APIs are not stable and do not guarantee backward compatibility.

THIS LIBRARY IS EXPERIMENTAL AND SUBJECT TO CHANGE.
