  823.     <p>Parse a size qualified by binary or metric units into <tt class="docutils literal"><span class="pre"><span class="Identifier">size</span></span></tt>.  This format is often called &quot;human readable&quot;.  Result is the number of processed chars or 0 on parse errors and size is rounded to the nearest integer.  Trailing garbage like &quot;/s&quot; in &quot;1k/s&quot; is allowed and detected by <tt class="docutils literal"><span class="pre"><span class="Identifier">result</span> <span class="Operator">&lt;</span> <span class="Identifier">s</span><span class="Operator">.</span><span class="Identifier">len</span></span></tt>.</p>
    824. 

  824. <p>To simplify use, following non-rare wild conventions, and since fractional data like milli-bytes is so rare, unit matching is case-insensitive but for the 'i' distinguishing binary-metric from metric (which cannot be 'I').</p>
    825. 

  825. <p>An optional trailing 'B|b' is ignored but processed.  I.e., you must still know if units are bytes | bits or infer this fact via the case of s<sup><strong><a class="reference internal" href="#footnote-1">[1]</a></strong></sup> (if users can even be relied upon to use 'B' for byte and 'b' for bit or have that be s<sup><strong><a class="reference internal" href="#footnote-1">[1]</a></strong></sup>).</p>
    826. 

  826. <p>If <tt class="docutils literal"><span class="pre"><span class="Identifier">alwaysBin</span><span class="Operator">==</span><span class="Identifier">true</span></span></tt> then scales are always binary-metric, but e.g. &quot;KiB&quot; is still accepted for clarity.  If the value would exceed the range of <tt class="docutils literal"><span class="pre"><span class="Identifier">int64</span></span></tt>, <tt class="docutils literal"><span class="pre"><span class="Identifier">size</span></span></tt> saturates to <tt class="docutils literal"><span class="pre"><span class="Identifier">int64</span><span class="Operator">.</span><span class="Identifier">high</span></span></tt>.  Supported metric prefix chars include k, m, g, t, p, e, z, y (but z &amp; y saturate unless the number is a small fraction).</p>
