    63. 

  63. <p>We begin with a variable <code>expr</code> of type <code>Expr</code> that has no fields
    64. 

  64. (because it is an enum), and by matching on it and rebinding a variable
    65. 

  65. with the same name <code>expr</code> we effectively imbue our variable with all of
    66. 

  66. the data fields provided by the variant that it turned out to be. So for
    67. 

  67. example above if we ended up in the <code>MethodCall</code> case then we get to use
    68. 

  68. <code>expr.receiver</code>, <code>expr.args</code> etc; if we ended up in the <code>IfLet</code> case we
    69. 

  69. get to use <code>expr.pat</code>, <code>expr.then_branch</code>, <code>expr.else_branch</code>.</p>
    70. 

  70. <p>The pattern is similar if the input expression is borrowed:</p>
    71. 

  71. 

  72. <pre class="rust rust-example-rendered">
    73. 

  73. <span class="kw">match</span> <span class="kw-2">*</span><span class="ident">expr</span> {

    75. 

  75. <p>This approach avoids repeating the variant names twice on every line.</p>

    79. 

  79. <p>In general, the name to which a syntax tree enum variant is bound should
    80. 

  80. be a suitable name for the complete syntax tree enum type.</p>
