From dbfcdd45c607762ee8371494ce8a6326086a9596 Mon Sep 17 00:00:00 2001 From: Alex Burka Date: Sun, 4 Dec 2016 15:56:51 -0500 Subject: [PATCH] reference: fix definition of :tt The reference says that $x:tt matches "either side of the `=>` in macro_rules` which is technically true but completely uninformative. This changes that bullet point to what the book says (a single token or sequence of token trees inside brackets). --- src/doc/reference.md | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/doc/reference.md b/src/doc/reference.md index 8655bab4b21..5d20738a1e3 100644 --- a/src/doc/reference.md +++ b/src/doc/reference.md @@ -603,7 +603,8 @@ syntax named by _designator_.
