bors 2b351c2db2 Auto merge of #1429 - gnzlbg:appveyor_reduce, r=gnzlbg 
Reduce appveyor churn

This should reduce the Appveyorn churn for other projects a bit more.

Please let me know if there is anything else that can be done. Maybe the infra team could discuss whether to document some general guidelines for rust-lang and rust-lang-nursery projects, and write them down somewhere. I would be willing to help.

libc - Raw FFI bindings to platforms' system libraries

libc provides all of the definitions necessary to easily interoperate with C code (or "C-like" code) on each of the platforms that Rust supports. This includes type definitions (e.g. c_int), constants (e.g. EINVAL) as well as function headers (e.g. malloc).

This crate exports all underlying platform types, functions, and constants under the crate root, so all items are accessible as libc::foo. The types and values of all the exported APIs match the platform that libc is compiled for.

More detailed information about the design of this library can be found in its associated RFC.

Usage

Add the following to your Cargo.toml:

[dependencies]
libc = "0.2"

Features

  • std: by default libc links to the standard library. Disable this feature remove this dependency and be able to use libc in #![no_std] crates.

  • extra_traits: all structs implemented in libc are Copy and Clone. This feature derives Debug, Eq, Hash, and PartialEq.

  • deprecated: use_std is deprecated, and is equivalent to std.

Rust version support

The minimum supported Rust toolchain version is Rust 1.13.0 . APIs requiring newer Rust features are only available on newer Rust toolchains:

Feature Version
union 1.19.0
const mem::size_of 1.24.0
repr(align) 1.25.0
extra_traits 1.25.0
core::ffi::c_void 1.30.0
repr(packed(N)) 1.33.0

Platform support

Platform-specific documentation (master branch).

See ci/build.sh for the platforms on which libc is guaranteed to build for each Rust toolchain. The test-matrix at Travis-CI, Appveyor, and Cirrus-CI show the platforms in which libc tests are run.
