We use cargo vendor to generate a .cargo/config file and the vendor directory. Vendoring allows us to lock our dependencies and to modify them easily from the top level Cargo.toml. We vendor all dependencies, including the crates.io ones, which allows for network isolated builds. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

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][rfc].
|
|
|
|
[rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1291-promote-libc.md
|
|
|
|
## Usage
|
|
|
|
Add the following to your `Cargo.toml`:
|
|
|
|
```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 `struct`s 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)][docs.master].
|
|
|
|
See
|
|
[`ci/build.sh`](https://github.com/rust-lang/libc/blob/master/libc-test/build.rs)
|
|
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.
