684aa2b7fd librustc: De-export ty. rs=deexporting 2013-01-30 12:18:08 -08:00

a30ea013f5 Handle supertrait calls in default methods
Add a new method_super origin for supertrait methods. Also make
coherence create a table that maps pairs of trait IDs and self types
to impl IDs, so that it's possible to check a supertrait method
knowing only its index in its trait's methods (without knowing all
supertraits for a given trait).

r=nmatsakis and graydon -- with hope, we'll revamp all of this code as
per #4678, but for now this fixes the bug.

Closes #3979

eb4d39e1fe libstd: Remove "dual impls" from the language and enforce coherence rules. r=brson
"Dual impls" are impls that are both type implementations and trait
implementations. They can lead to ambiguity and so this patch removes them
from the language.

This also enforces coherence rules. Without this patch, records can implement
traits not defined in the current crate. This patch fixes this, and updates
all of rustc to adhere to the new enforcement. Most of this patch is fixing
rustc to obey the coherence rules, which involves converting a bunch of records
to structs.

2e10ea58c3 Integrate vec patterns into borrow checker.
The tail portion of the pattern effectively borrows a vector,
but the borrow checker knew nothing about this.

d4fd30c6ac Link the lifetimes of regions resulting from borrows of the
contents of other borrowed pointers to the lifetimes of the
borrowed value.  Fixes #3148.

42095221f4 Properly suppress derived type error messages
Previously, the typechecker suppressed many but not all errors,
by suppressing errors where the actual type was either ty_err, or
a function type whose result was ty_err. Added a has_ty_err flag
to the type flags so as to suppress errors for any types involving
ty_err.

737e115646 mode: reset mode on entry to fn body.
This is an interim fix to address the "Beware!" unsoundness.  I have a
more comprehensive rewrite of mode.rs in the pipeline.

2b92962aa2 A collection of refactorings that I found it hard/tiresome to divide:
- Make `extern fn()` assignable to any closure type, rather than
  a subtype.
- Remove unused int_ty_set and float_ty_set
- Refactor variable unification and make it more DRY
- Do fn sub/lub/glb on the level of fn_sig
- Rename infer::to_str::ToStr to infer::to_str::InferStr
- Capitalize names of various types
- Correct hashing of FnMeta
- Convert various records-of-fns into structs-of-fns.  This is both
  eliminating use of deprecated features and more forwards compatible
  with fn reform.

0046ed9462 Remove un-needed code for obsolete classes
and rename "class" to "struct" everywhere possible (except local
vars, I was too lazy for that) -- that is why this commit is so

No review, just dead code removal and renaming.
