cxx-build 1.0.131

The CXX code generator for constructing and compiling C++ code. This is intended to be used from Cargo build scripts to execute CXX's C++ code generator, set up any additional compiler flags depending on the use case, and make the C++ compiler invocation.
# Example Example of a canonical Cargo build script that builds a CXX bridge: ```no_run // build.rs fn main() { cxx_build::bridge("src/main.rs") .file("src/demo.cc") .std("c++11") .compile("cxxbridge-demo"); println!("cargo:rerun-if-changed=src/main.rs"); println!("cargo:rerun-if-changed=src/demo.cc"); println!("cargo:rerun-if-changed=include/demo.h"); } ``` A runnable working setup with this build script is shown in the *demo* directory of [https://github.com/dtolnay/cxx].

# Alternatives For use in non-Cargo builds like Bazel or Buck, CXX provides an alternate way of invoking the C++ code generator as a standalone command line tool. The tool is packaged as the `cxxbridge-cmd` crate. ```bash $ cargo install cxxbridge-cmd # or build it from the repo $ cxxbridge src/main.rs --header > path/to/mybridge.h $ cxxbridge src/main.rs > path/to/mybridge.cc ```
