<p>Header field names identify the header. Header sets may include multiple

headers with the same name. The HTTP specification defines a number of
|
||
standard headers, but HTTP messages may include non-standard header names as
|
||
well as long as they adhere to the specification.</p>
|
||
<p><code>HeaderName</code> is used as the <a href="struct.HeaderMap.html"><code>HeaderMap</code></a> key. Constants are available for

all standard header names in the <a href="index.html"><code>header</code></a> module.</p>

<p><code>HeaderName</code> represents standard header names using an <code>enum</code>, as such they

will not require an allocation for storage. All custom header names are
|

lower cased upon conversion to a <code>HeaderName</code> value. This avoids the
|
||
overhead of dynamically doing lower case conversion during the hash code
|
||
computation and the comparison operation.</p>
