From 742ec4b9bf7ae7d693da7fe75e5f974e0fafb9d0 Mon Sep 17 00:00:00 2001 From: Mazdak Farrokhzad Date: Tue, 8 Oct 2019 22:17:46 +0200 Subject: ast: remove implicit pprust dependency via Display. Instead just use `pprust::path_to_string(..)` where needed. This has two benefits: a) The AST definition is now independent of printing it. (Therefore we get closer to extracting a data-crate.) b) Debugging should be easier as program flow is clearer. --- src/libsyntax/parse/parser/expr.rs | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'src/libsyntax/parse/parser') diff --git a/src/libsyntax/parse/parser/expr.rs b/src/libsyntax/parse/parser/expr.rs index b459782d237..660bf9b7d65 100644 --- a/src/libsyntax/parse/parser/expr.rs +++ b/src/libsyntax/parse/parser/expr.rs @@ -552,8 +552,11 @@ impl<'a> Parser<'a> { // Report non-fatal diagnostics, keep `x as usize` as an expression // in AST and continue parsing. - let msg = format!("`<` is interpreted as a start of generic \ - arguments for `{}`, not a {}", path, op_noun); + let msg = format!( + "`<` is interpreted as a start of generic arguments for `{}`, not a {}", + pprust::path_to_string(&path), + op_noun, + ); let span_after_type = parser_snapshot_after_type.token.span; let expr = mk_expr(self, P(Ty { span: path.span, -- cgit 1.4.1-3-g733a5
