|
|||
|
|
<p>The main idea of this type is to provide something that can index memory,
|
|||
|
|
but uses less memory than <code>usize</code> on 64-bit systems. Specifically, its
|
|||
|
|
representation is always a <code>u32</code> and has <code>repr(transparent)</code> enabled. (So
|
|||
|
|
it is safe to transmute between a <code>u32</code> and a <code>SmallIndex</code>.)</p>
|
|||
|
|
<p>A small index is typically useful in cases where there is no practical way
|
|||
|
|
that the index will overflow a 32-bit integer. A good example of this is
|
|||
|
|
an NFA state. If you could somehow build an NFA with <code>2^30</code> states, its
|
|||
|
|
memory usage would be exorbitant and its runtime execution would be so
|
|||
|
|
slow as to be completely worthless. Therefore, this crate generally deems
|
|||
|
|
it acceptable to return an error if it would otherwise build an NFA that
|
|||
|
|
requires a slice longer than what a 32-bit integer can index. In exchange,
|
|||
|
|
we can use 32-bit indices instead of 64-bit indices in various places.</p>
|
|||
|
|
<p>This type ensures this by providing a constructor that will return an error
|
|||
|
|
if its argument cannot fit into the type. This makes it much easier to
|
|||
|
|
handle these sorts of boundary cases that are otherwise extremely subtle.</p>
|
|||
|
|
<p>On all targets, this type guarantees that its value will fit in a <code>u32</code>,
|
|||
|
|
<code>i32</code>, <code>usize</code> and an <code>isize</code>. This means that on 16-bit targets, for
|
|||
|
|
example, this type’s maximum value will never overflow an <code>isize</code>,
|
|||
|
|
which means it will never overflow a <code>i16</code> even though its internal
|
|||
|
|
representation is still a <code>u32</code>.</p>
|
|||
|
|
<p>The purpose for making the type fit into even signed integer types like
|
|||
|
|
<code>isize</code> is to guarantee that the difference between any two small indices
|
|||
|
|
is itself also a small index. This is useful in certain contexts, e.g.,
|
|||
|
|
for delta encoding.</p>
|
|||
|
|
<h2 id="other-types"><a href="#other-types">Other types</a></h2>
|
|||
|
|
<p>The following types wrap <code>SmallIndex</code> to provide a more focused use case:</p>
|
|||
|
|
<ul>
|
|||
|
|
<li><a href="../../struct.PatternID.html" title="struct regex_automata::PatternID"><code>PatternID</code></a> is for representing the identifiers of patterns.</li>
|
|||
|
|
<li><a href="struct.StateID.html" title="struct regex_automata::util::primitives::StateID"><code>StateID</code></a> is for representing the identifiers of states in finite
|
|||
|
|
automata. It is used for both NFAs and DFAs.</li>
|
|||
|
|
</ul>
|
|||
|
|
<h2 id="representation"><a href="#representation">Representation</a></h2>
|
|||
|
|
<p>This type is always represented internally by a <code>u32</code> and is marked as
|
|||
|
|
<code>repr(transparent)</code>. Thus, this type always has the same representation as
|
|||
|
|
a <code>u32</code>. It is thus safe to transmute between a <code>u32</code> and a <code>SmallIndex</code>.</p>
|
|||
|
|
<h2 id="indexing"><a href="#indexing">Indexing</a></h2>
|
|||
|
|
<p>For convenience, callers may use a <code>SmallIndex</code> to index slices.</p>
|
|||
|
|
<h2 id="safety"><a href="#safety">Safety</a></h2>
|
|||
|
|
<p>While a <code>SmallIndex</code> is meant to guarantee that its value fits into <code>usize</code>
|
|||
|
|
without using as much space as a <code>usize</code> on all targets, callers must
|
|||
|
|
not rely on this property for safety. Callers may choose to rely on this
|
|||
|
|
property for correctness however. For example, creating a <code>SmallIndex</code> with
|
|||
|
|
an invalid value can be done in entirely safe code. This may in turn result
|
|||
|
|
in panics or silent logical errors.</p>
