From 5cccf3cd256420d9f32c265e83036dea1d5f94d8 Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Wed, 29 Jul 2015 17:01:14 -0700 Subject: syntax: Implement #![no_core] This commit is an implementation of [RFC 1184][rfc] which tweaks the behavior of the `#![no_std]` attribute and adds a new `#![no_core]` attribute. The `#![no_std]` attribute now injects `extern crate core` at the top of the crate as well as the libcore prelude into all modules (in the same manner as the standard library's prelude). The `#![no_core]` attribute disables both std and core injection.
