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 2015-01-16 10:55:24 -08:00			`#![feature(start)]`
Implement native::IoFactory This commit re-organizes the io::native module slightly in order to have a working implementation of rtio::IoFactory which uses native implementations. The goal is to seamlessly multiplex among libuv/native implementations wherever necessary. Right now most of the native I/O is unimplemented, but we have existing bindings for file descriptors and processes which have been hooked up. What this means is that you can now invoke println!() from libstd with no local task, no local scheduler, and even without libuv. There's still plenty of work to do on the native I/O factory, but this is the first steps into making it an official portion of the standard library. I don't expect anyone to reach into io::native directly, but rather only std::io primitives will be used. Each std::io interface seamlessly falls back onto the native I/O implementation if the local scheduler doesn't have a libuv one (hurray trait ojects!) 2013-11-12 14:38:28 -08:00

Mass rename uint/int to usize/isize Now that support has been removed, all lingering use cases are renamed. 2015-03-25 17:06:52 -07:00			`pub fn main(_: isize, _: const const u8) -> isize {`
