key.</p>
<p><code>my_private_key</code> is the ephemeral private key to use. Since it is moved, it
will not be usable after calling <code>agree_ephemeral</code>, thus guaranteeing that
the key is used for only one key agreement.</p>
<p><code>peer_public_key_alg</code> is the algorithm/curve for the peer&#39;s public key
point; <code>agree_ephemeral</code> will return <code>Err(error_value)</code> if it does not
match <code>my_private_key&#39;s</code> algorithm/curve.</p>
<p><code>peer_public_key</code> is the peer&#39;s public key. <code>agree_ephemeral</code> verifies that
it is encoded in the standard form for the algorithm and that the key is
<em>valid</em>; see the algorithm&#39;s documentation for details on how keys are to
be encoded and what constitutes a valid key for that algorithm.</p>
<p><code>error_value</code> is the value to return if an error occurs before <code>kdf</code> is
called, e.g. when decoding of the peer&#39;s public key fails or when the public
key is otherwise invalid.</p>
<p>After the key agreement is done, <code>agree_ephemeral</code> calls <code>kdf</code> with the raw
key material from the key agreement operation and then returns what <code>kdf</code>
returns.</p>
<p>C analogs: <code>EC_POINT_oct2point</code> + <code>ECDH_compute_key</code>, <code>X25519</code>.</p>

<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>)
