<p>We begin with a variable <code>expr</code> of type <code>Expr</code> that has no fields
|
||
|
|
(because it is an enum), and by matching on it and rebinding a variable
|
||
|
|
with the same name <code>expr</code> we effectively imbue our variable with all of
|
||
|
|
the data fields provided by the variant that it turned out to be. So for
|
||
|
|
example above if we ended up in the <code>MethodCall</code> case then we get to use
|
||
|
|
<code>expr.receiver</code>, <code>expr.args</code> etc; if we ended up in the <code>If</code> case we get
|
||
|
|
to use <code>expr.cond</code>, <code>expr.then_branch</code>, <code>expr.else_branch</code>.</p>
|
||
|
|
<p>This approach avoids repeating the variant names twice on every line.</p>

|

|
|
<p>Rust grammar has an ambiguity where braces sometimes turn a path
|

|
expression into a struct initialization and sometimes do not. In the
|
||
|
|
following code, the expression <code>S {}</code> is one expression. Presumably
|

there is an empty struct <code>struct S {}</code> defined somewhere which it is

instantiating.</p>

<p>We would want to parse the above using <code>Expr::parse</code> after the <code>=</code>
|
||
|
|
token.</p>
|
||
|
|
<p>But in the following, <code>S {}</code> is <em>not</em> a struct init expression.</p>
|
||

<div class="example-wrap"><pre class="rust rust-example-rendered">

|

<p>For that reason we would want to parse if-conditions using
|

<code>Expr::parse_without_eager_brace</code> after the <code>if</code> token. Same for
|

similar syntactic positions such as the condition expr after a

<code>while</code> token or the expr at the top of a <code>match</code>.</p>

<p>The Rust grammar's choices around which way this ambiguity is
|

resolved at various syntactic positions is fairly arbitrary. Really
|
||
|

either parse behavior could work in most positions, and language
|
||
|
|
designers just decide each case based on which is more likely to be
|

what the programmer had in mind most of the time.</p>

<p>Note the grammar ambiguity on trailing braces is distinct from
|
||
|
|
precedence and is not captured by assigning a precedence level to
|
||
|
|
the braced struct init expr in relation to other operators. This can
|
||
|
|
be illustrated by <code>return 0..S {}</code> vs <code>match 0..S {}</code>. The former
|
||
|
|
parses as <code>return (0..(S {}))</code> implying tighter precedence for
|
||
|
|
struct init than <code>..</code>, while the latter parses as <code>match (0..S) {}</code>
|
||
|
|
implying tighter precedence for <code>..</code> than struct init, a
|
||
|
|
contradiction.</p>
