From 235f35b0b724a38a5583112825d46f50c5dde980 Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Tue, 17 Feb 2015 13:58:34 -0800 Subject: std: Stabilize the `ascii` module This commit performs a stabilization pass over the `std::ascii` module taking the following actions: * the module name is now stable * `AsciiExt` is now stable after moving its type parameter to an `Owned` associated type * `AsciiExt::is_ascii` is now stable * `AsciiExt::to_ascii_uppercase` is now stable * `AsciiExt::to_ascii_lowercase` is now stable * `AsciiExt::eq_ignore_ascii_case` is now stable * `AsciiExt::make_ascii_uppercase` is added to possibly replace `OwnedAsciiExt::into_ascii_uppercase` (similarly for lowercase variants). * `escape_default` now returns an iterator and is stable * `EscapeDefault` is now stable Trait implementations are now also marked stable. Primarily it is still unstable to *implement* the `AsciiExt` trait due to it containing some unstable methods.
