c_import
This is a small proc macro crate providing a c_import macro (also a cpp_import macro), which can be used to import C headers into your program. It leverages bindgen, so bindgen needs to be installed in your system.
Usage
In your Cargo.toml:
# Cargo.toml
[]
= "0.1"
In your Rust source file:
// src/main.rs
use c_importc_import;
c_import!;
In your Rust build script:
// build.rs
Using non-system headers is also possible via enclosing the header path with quotation marks:
// src/main.rs
use c_importc_import;
c_import!;
Extra clang arguments
You can pass extra clang arguments as extra arguments to the macro:
// src/main.rs
use c_importc_import;
c_import!;
Usage with C++ headers (limited)
// src/main.rs
use c_import cpp_import;
cpp_import!;
// build.rs
Another example showing how to deal with C++ namespaces:
// src/my_header.hpp
// src/main.rs
use c_import cpp_import;
cpp_import!;
Limitations
- Mostly bindgen limitations with C++ headers.
