From 689f19722fabd9aab61e826e00140a7fe7084afa Mon Sep 17 00:00:00 2001 From: Huon Wilson Date: Sun, 2 Mar 2014 12:59:35 +1100 Subject: rand: deprecate `rng`. This should be called far less than it is because it does expensive OS interactions and seeding of the internal RNG, `task_rng` amortises this cost. The main problem is the name is so short and suggestive. The direct equivalent is `StdRng::new`, which does precisely the same thing. The deprecation will make migrating away from the function easier. --- src/libsyntax/parse/token.rs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/libsyntax') diff --git a/src/libsyntax/parse/token.rs b/src/libsyntax/parse/token.rs index 71ee32b4aad..cd52ff4b0ac 100644 --- a/src/libsyntax/parse/token.rs +++ b/src/libsyntax/parse/token.rs @@ -670,7 +670,7 @@ pub fn fresh_name(src: &ast::Ident) -> Name { // following: debug version.
