|

Returns <code>Ok</code> when the entire string has been parsed (otherwise <code>parsed</code> should not be used).
|
||
There should be no trailing string after parsing;
|
||
use a stray <a href="./enum.Item.html#variant.Space"><code>Item::Space</code></a> to trim whitespaces.</p>
|
||
<p>This particular date and time parser is:</p>
|
||
<ul>
|
||
<li>
|
||
<p>Greedy. It will consume the longest possible prefix.
|
||
For example, <code>April</code> is always consumed entirely when the long month name is requested;
|
||
it equally accepts <code>Apr</code>, but prefers the longer prefix in this case.</p>
|
||
</li>
|
||
<li>
|
||
<p>Padding-agnostic (for numeric items).
|
||
The <a href="./enum.Pad.html"><code>Pad</code></a> field is completely ignored,
|
||
so one can prepend any number of whitespace then any number of zeroes before numbers.</p>
|
||
</li>
|
||
<li>
|
||
<p>(Still) obeying the intrinsic parsing width. This allows, for example, parsing <code>HHMMSS</code>.</p>
