|
|||
|
|
<p>Implementors of the <code>Read</code> trait are called 'readers'.</p>
|
|||
|
|
<p>Readers are defined by one required method, <a href="trait.Read.html#tymethod.read"><code>read()</code></a>. Each call to <a href="trait.Read.html#tymethod.read"><code>read()</code></a>
|
|||
|
|
will attempt to pull bytes from this source into a provided buffer. A
|
|||
|
|
number of other methods are implemented in terms of <a href="trait.Read.html#tymethod.read"><code>read()</code></a>, giving
|
|||
|
|
implementors a number of ways to read bytes while only needing to implement
|
|||
|
|
a single method.</p>
|
|||
|
|
<p>Readers are intended to be composable with one another. Many implementors
|
|||
|
|
throughout <a href="../../std/io/index.html"><code>std::io</code></a> take and provide types which implement the <code>Read</code>
|
|||
|
|
trait.</p>
|
|||
|
|
<p>Please note that each call to <a href="trait.Read.html#tymethod.read"><code>read()</code></a> may involve a system call, and
|
|||
|
|
therefore, using something that implements <a href="trait.BufRead.html"><code>BufRead</code></a>, such as
|
|||
|
|
<a href="struct.BufReader.html"><code>BufReader</code></a>, will be more efficient.</p>

that the buffer <code>buf</code> has been filled in with <code>n</code> bytes of data from this

<h2>Search Tricks</h2>
|
|||
|
|
|
|||
|
|
<p>
|
|||
|
|
Prefix searches with a type followed by a colon (e.g.
|
|||
|
|
<code>fn:</code>) to restrict the search to a given type.
|
|||
|
|
</p>
|
|||
|
|
|
|||
|
|
<p>
|
|||
|
|
Accepted types are: <code>fn</code>, <code>mod</code>,
|
|||
|
|
<code>struct</code>, <code>enum</code>,
|
|||
|
|
<code>trait</code>, <code>type</code>, <code>macro</code>,
|
|||
|
|
and <code>const</code>.
|
|||
|
|
</p>
|
|||
|
|
|
|||
|
|
<p>
|
|||
|
|
Search functions by type signature (e.g.
|
|||
|
|
<code>vec -> usize</code> or <code>* -> vec</code>)
|
|||
|
