<p>Sharing is implemented with a <a href="struct.AtomicDevice.html" title="struct embedded_hal_bus::i2c::AtomicDevice"><code>AtomicDevice</code></a>, which consists of an <code>UnsafeCell</code> and an <code>AtomicBool</code> “locked” flag.
This means it has low overhead, like <a href="struct.RefCellDevice.html" title="struct embedded_hal_bus::i2c::RefCellDevice"><code>RefCellDevice</code></a>. Aditionally, it is <code>Send</code>,
which allows sharing a single bus across multiple threads (interrupt priority level), like <a href="struct.CriticalSectionDevice.html" title="struct embedded_hal_bus::i2c::CriticalSectionDevice"><code>CriticalSectionDevice</code></a>,
while not using critical sections and therefore impacting real-time performance less.</p>
<p>The downside is using a simple <code>AtomicBool</code> for locking doesnt prevent two threads from trying to lock it at once.
For example, the main thread can be doing an I2C transaction, and an interrupt fires and tries to do another. In this
case, a <code>Busy</code> error is returned that must be handled somehow, usually dropping the data or trying again later.</p>
<p>Note that retrying in a loop on <code>Busy</code> errors usually leads to deadlocks. In the above example, itll prevent the
interrupt handler from returning, which will starve the main thread and prevent it from releasing the lock. If
this is an issue for your use case, you most likely should use <a href="struct.CriticalSectionDevice.html" title="struct embedded_hal_bus::i2c::CriticalSectionDevice"><code>CriticalSectionDevice</code></a> instead.</p>
<p>This primitive is particularly well-suited for applications that have external arbitration
rules that prevent <code>Busy</code> errors in the first place, such as the RTIC framework.</p>
