c71970eea2 Extract attribute handling code into a module 
This commit causes no change in trans semantics, it just moves some functions around and
deduplicates them.

37601131a0 Make the Fn traits inherit from one another and remove the bridging 
impls.

This requires:

1. modifying trait selection a bit so that when we synthesize impls for
   fn pointers and closures;
2. adding code to trans so that we can synthesize a `FnMut`/`FnOnce`
   impl for a `Fn` closure and so forth.

00fcf79448 Remove the synthetic "region bound" from closures and instead update how 
type-outlives works for closure types so that it ensures that all upvars
outlive the region in question. This gives the same guarantees but
without introducing artificial regions (and gives better error messages
to boot).

44440e5c18 core: split into fmt::Show and fmt::String 
fmt::Show is for debugging, and can and should be implemented for
all public types. This trait is used with `{:?}` syntax. There still
exists #[derive(Show)].

fmt::String is for types that faithfully be represented as a String.
Because of this, there is no way to derive fmt::String, all
implementations must be purposeful. It is used by the default format
syntax, `{}`.

This will break most instances of `{}`, since that now requires the type
to impl fmt::String. In most cases, replacing `{}` with `{:?}` is the
correct fix. Types that were being printed specifically for users should
receive a fmt::String implementation to fix this.

Part of #20013

2486d93e5b Fix ICE that @steveklabnik encountered in rust-ice. The problems turned out to be that were being very loose with bound regions in trans (we were basically just ignoring and flattening binders). Since binders are significant to subtyping and hence to trait selection, this can cause a lot of problems. So this patch makes us treat them more strictly -- for example, we propagate binders, and avoid skipping past the Binder by writing foo.0. 
Fixes #20644.

1205fd88df Centralize on using Binder to introduce new binding levels, rather than having FnSig carry an implicit binding level. This means that we be more typesafe in general, since things that instantiate bound regions can drop the Binder to reflect that. 2014-12-19 03:29:30 -05:00

096a28607f librustc: Make Copy opt-in. 
This change makes the compiler no longer infer whether types (structures
and enumerations) implement the `Copy` trait (and thus are implicitly
copyable). Rather, you must implement `Copy` yourself via `impl Copy for
MyType {}`.

A new warning has been added, `missing_copy_implementations`, to warn
you if a non-generic public type has been added that could have
implemented `Copy` but didn't.

For convenience, you may *temporarily* opt out of this behavior by using
`#![feature(opt_out_copy)]`. Note though that this feature gate will never be
accepted and will be removed by the time that 1.0 is released, so you should
transition your code away from using it.

This breaks code like:

    #[deriving(Show)]
    struct Point2D {
        x: int,
        y: int,
    }

    fn main() {
        let mypoint = Point2D {
            x: 1,
            y: 1,
        };
        let otherpoint = mypoint;
        println!("{}{}", mypoint, otherpoint);
    }

Change this code to:

    #[deriving(Show)]
    struct Point2D {
        x: int,
        y: int,
    }

    impl Copy for Point2D {}

    fn main() {
        let mypoint = Point2D {
            x: 1,
            y: 1,
        };
        let otherpoint = mypoint;
        println!("{}{}", mypoint, otherpoint);
    }

This is the backwards-incompatible part of #13231.

Part of RFC #3.
