flat_map_ produces an iterator that maps each element to an iterator,
and yields the elements of the produced iterators.
This is the monadic bind :: M a -> (a -> M b) -> M b for iterators.
Named just like the vec method, but with a trailing underline until the
method resolution bug is resolved.
the `test/run-pass/class-trait-bounded-param.rs` test was xfailed and
written in an ancient dialect of Rust so I've just removed it
this also removes `to_vec` from DList because it's provided by
`std::iter::to_vec`
an Iterator implementation is added for OptVec but some transitional
internal iterator methods are still left
This pull request contains an unoptimized implementation of most of the SHA-2 functions (everything but the variable output size versions). I also created a common trait (Digest) for all of the interesting methods for working with digests and updated the existing SHA-1 code to use it. Finally, while working with the SHA-1 code, I got rid of the use of @ types and type objects.
I've tested all functions against the Wikipedia test vectors. Additionally, I tested the SHA-512, 384, and 256 variants against the Java implementations of those digests.
I did my best to try to follow Rust conventions, but, there are so many different conventions in the code base right now that I'm not sure if I'm following the correct one or not. Anyway, I'm happy to rework if I didn't get the coding convention right (or if there are bugs!).

* Rename struct Sha1State to Sha1
* Remove all use of @ types
* Use fixed length vectors
* Move all of the inner functions from inside sha1() to top level, private functions
* Sha1 instances are now created via Sha1::new()
* Update all constant names to uppercase
* Remove unecessary assert_eq!s
* Remove check_vec_eq() helper function; use vec::eq() instead
This commit adds filtered method for Option type. It is not exactly necessary (chain method can be used instead), however I believe that this approach using extra filtered method is more convinient.
To achieve this, the following changes were made:
* Move TyDesc, TyVisitor and Opaque to std::unstable::intrinsics
* Convert TyDesc, TyVisitor and Opaque to lang items instead of specially
handling the intrinsics module
* Removed TypeDesc, FreeGlue and get_type_desc() from sys
Fixes#3475.
This fixes part of #3730, but not all.
Also changes the TyDesc struct to be equivalent with the generated
code, with the hope that the above issue may one day be closed for good,
i.e. that the TyDesc type can completely be specified in the Rust
sources and not be generated.
