<p>This type of lock allows a number of readers or at most one writer at any
|
|||
|
|
point in time. The write portion of this lock typically allows modification
|
|||
|
|
of the underlying data (exclusive access) and the read portion of this lock
|
|||
|
|
typically allows for read-only access (shared access).</p>
|
|||
|
|
<p>The type parameter <code>T</code> represents the data that this lock protects. It is
|
|||
|
|
required that <code>T</code> satisfies <code>Send</code> to be shared across threads and <code>Sync</code> to
|
|||
|
|
allow concurrent access through readers. The RAII guards returned from the
|
|||
|
|
locking methods implement <code>Deref</code> (and <code>DerefMut</code> for the <code>write</code> methods)
|
|||
|
|
to allow access to the contained of the lock.</p>
