<p>This gives a uniform distribution (assuming the RNG used to sample
|

it is itself uniform & the <code>SampleRange</code> implementation for the
|
||
given type is correct), even for edge cases like <code>low = 0u8</code>,
|

<code>high = 170u8</code>, for which a naive modulo operation would return
|
||
numbers less than 85 with double the probability to those greater

than 85.</p>
|

|

<p>Types should attempt to sample in <code>[low, high)</code>, i.e., not

including <code>high</code>, but this may be very difficult. All the

primitive integer types satisfy this property, and the float types

normally satisfy it, but rounding may mean <code>high</code> can occur.</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>)
