<p>Dylan: create Rust declare variable</p> <hr /> <div>== Declaring a variable ==<br /> The syntax for declaring variables in Rust is:&lt;syntaxhighlight lang=&quot;rust&quot;&gt;<br /> let VARIABLE_NAME: TYPE;<br /> &lt;/syntaxhighlight&gt;The &lt;code&gt;VARIABLE_NAME&lt;/code&gt; should be set to any alpha-numerical string, and can also include underscores. See [[naming variables]] for a guide on how to name variables, and [[Rust identifier naming conventions]] for advice on common conventions.<br /> <br /> === Example of declaring a variable ===<br /> &lt;syntaxhighlight lang=&quot;rust&quot;&gt;<br /> let name: String;<br /> &lt;/syntaxhighlight&gt;<br /> <br /> == Declare and initialize together ==<br /> You can also both create (declare) and initialize (set the value of) a variable in one line:&lt;syntaxhighlight lang=&quot;rust&quot;&gt;<br /> let VARIABLE_NAME: TYPE = VALUE;<br /> &lt;/syntaxhighlight&gt;There is more info on initializing variables in Rust on the [[Rust initialize variable]] page.<br /> <br /> === Example of declaring and initializing a variable ===<br /> &lt;syntaxhighlight lang=&quot;rust&quot;&gt;<br /> let town: &amp;str = &quot;Paris&quot;;<br /> &lt;/syntaxhighlight&gt;<br /> <br /> == Type inference ==<br /> The Rust compiler is clever enough to ''infer'' the type of a variable based on the value we assign it.<br /> <br /> We still need to give it a value at some point, otherwise it's impossible for the compiler to know what type to give it.<br /> <br /> === Example of type inference ===<br /> &lt;syntaxhighlight lang=&quot;rust&quot;&gt;<br /> let age = 21;<br /> &lt;/syntaxhighlight&gt;In this example, the compiler will ''infer'' that the type of &lt;code&gt;age&lt;/code&gt; is an &lt;code&gt;i32&lt;/code&gt;, a signed 32-bit integer (number).</div>
