//! # The Rust standard library
//!
//! The Rust standard library is a group of interrelated modules defining
//! the core language traits, operations on built-in data types, collections,
//! platform abstractions, the task scheduler, runtime support for language
//! features and other common functionality.
//!
//! `std` includes modules corresponding to each of the integer types,
//! each of the floating point types, the `bool` type, tuples, characters,
//! strings (`str`), vectors (`vec`), managed boxes (`managed`), owned
//! boxes (`owned`), and unsafe and borrowed pointers (`ptr`, `borrowed`).
//! Additionally, `std` provides pervasive types (`option` and `result`),
//! task creation and communication primitives (`task`, `comm`), platform
2013-11-11 07:46:32 +01:00
//! abstractions (`os` and `path`), basic I/O abstractions (`io`), common
//! traits (`kinds`, `ops`, `cmp`, `num`, `to_str`), and complete bindings
//! to the C standard library (`libc`).
//!
//! # Standard library injection and the Rust prelude
//!
//! `std` is imported at the topmost level of every crate by default, as
//! if the first line of each crate was
//!
//! extern mod std;
//!
//! This means that the contents of std can be accessed from any context
//! with the `std::` path prefix, as in `use std::vec`, `use std::task::spawn`,
//! etc.
//!
//! Additionally, `std` contains a `prelude` module that reexports many of the
//! most common types, traits and functions. The contents of the prelude are
//! imported into every *module* by default. Implicitly, all modules behave as if
//! they contained the following prologue:
//!
//! use std::prelude::*;

Add generation of static libraries to rustc This commit implements the support necessary for generating both intermediate and result static rust libraries. This is an implementation of my thoughts in https://mail.mozilla.org/pipermail/rust-dev/2013-November/006686.html. When compiling a library, we still retain the "lib" option, although now there are "rlib", "staticlib", and "dylib" as options for crate_type (and these are stackable). The idea of "lib" is to generate the "compiler default" instead of having too choose (although all are interchangeable). For now I have left the "complier default" to be a dynamic library for size reasons. Of the rust libraries, lib{std,extra,rustuv} will bootstrap with an rlib/dylib pair, but lib{rustc,syntax,rustdoc,rustpkg} will only be built as a dynamic object. I chose this for size reasons, but also because you're probably not going to be embedding the rustc compiler anywhere any time soon. Other than the options outlined above, there are a few defaults/preferences that are now opinionated in the compiler: * If both a .dylib and .rlib are found for a rust library, the compiler will prefer the .rlib variant. This is overridable via the -Z prefer-dynamic option * If generating a "lib", the compiler will generate a dynamic library. This is overridable by explicitly saying what flavor you'd like (rlib, staticlib, dylib). * If no options are passed to the command line, and no crate_type is found in the destination crate, then an executable is generated With this change, you can successfully build a rust program with 0 dynamic dependencies on rust libraries. There is still a dynamic dependency on librustrt, but I plan on removing that in a subsequent commit. This change includes no tests just yet. Our current testing infrastructure/harnesses aren't very amenable to doing flavorful things with linking, so I'm planning on adding a new mode of testing which I believe belongs as a separate commit. Closes #552

rustdoc: Generate hyperlinks between crates The general idea of hyperlinking between crates is that it should require as little configuration as possible, if any at all. In this vein, there are two separate ways to generate hyperlinks between crates: 1. When you're generating documentation for a crate 'foo' into folder 'doc', then if foo's external crate dependencies already have documented in the folder 'doc', then hyperlinks will be generated. This will work because all documentation is in the same folder, allowing links to work seamlessly both on the web and on the local filesystem browser. The rationale for this use case is a package with multiple libraries/crates that all want to link to one another, and you don't want to have to deal with going to the web. In theory this could be extended to have a RUST_PATH-style searching situtation, but I'm not sure that it would work seamlessly on the web as it does on the local filesystem, so I'm not attempting to explore this case in this pull request. I believe to fully realize this potential rustdoc would have to be acting as a server instead of a static site generator. 2. One of foo's external dependencies has a #[doc(html_root_url = "...")] attribute. This means that all hyperlinks to the dependency will be rooted at this url. This use case encompasses all packages using libstd/libextra. These two crates now have this attribute encoded (currently at the /doc/master url) and will be read by anything which has a dependency on libstd/libextra. This should also work for arbitrary crates in the wild that have online documentation. I don't like how the version is hard-wired into the url, but I think that this may be a case-by-case thing which doesn't end up being too bad in the long run. Closes #9539
