From 38cb91e66ca7fc7374909b31598dab09db37edaa Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Fri, 16 Jan 2015 10:55:24 -0800 Subject: syntax: Feature gate #[start] and #[main] These two attributes are used to change the entry point into a Rust program, but for now they're being put behind feature gates until we have a chance to think about them a little more. The #[start] attribute specifically may have its signature changed. This is a breaking change to due the usage of these attributes generating errors by default now. If your crate is using these attributes, add this to your crate root: #![feature(start)] // if you're using the #[start] attribute #![feature(main)] // if you're using the #[main] attribute cc #20064 --- src/doc/trpl/unsafe.md | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'src/doc') diff --git a/src/doc/trpl/unsafe.md b/src/doc/trpl/unsafe.md index 075340660df..aac0e29170d 100644 --- a/src/doc/trpl/unsafe.md +++ b/src/doc/trpl/unsafe.md @@ -447,7 +447,7 @@ in the same format as C: ``` #![no_std] -#![feature(lang_items)] +#![feature(lang_items, start)] // Pull in the system libc library for what crt0.o likely requires extern crate libc; @@ -475,7 +475,7 @@ compiler's name mangling too: ```ignore #![no_std] #![no_main] -#![feature(lang_items)] +#![feature(lang_items, start)] extern crate libc; @@ -529,7 +529,7 @@ vectors provided from C, using idiomatic Rust practices. ``` #![no_std] -#![feature(lang_items)] +#![feature(lang_items, start)] # extern crate libc; extern crate core; @@ -653,7 +653,7 @@ sugar for dynamic allocations via `malloc` and `free`: ``` #![no_std] -#![feature(lang_items, box_syntax)] +#![feature(lang_items, box_syntax, start)] extern crate libc; -- cgit 1.4.1-3-g733a5
