|
||
|
|
<p>This macro will generate an implementation of the <code>BitRange</code> trait for an existing single
|
||
|
|
element tuple struct.</p>
|
||
|
|
<p>The syntax is more or less the same as declaring a “newtype”, <strong>without</strong> the attributes,
|
||
|
|
documentation comments and pub keyword.</p>
|
||
|
|
<p>The difference with a normal “newtype” is the type in parentheses. If the type is <code>[t]</code> (where
|
||
|
|
<code>t</code> is any of the unsigned integer type), the “newtype” will be generic and implement
|
||
|
|
<code>BitRange</code> for <code>T: AsMut<[t]> + AsRef<[t]></code> (for example a slice, an array or a <code>Vec</code>). You can
|
||
|
|
also use <code>MSB0 [t]</code>. The difference will be the positions of the bit. You can use the
|
||
|
|
<code>bits_positions</code> example to see where each bits is. If the type is neither of this two, the
|
||
|
|
“newtype” will wrap a value of the specified type and implements <code>BitRange</code> the same ways as
|
||
|
|
the wrapped type.</p>
