cxxbridge1
Generate c++ code from rust source files
Overview
Usage:
- cxxbridge <input>.rs
-
Emit .cc file for bridge to stdout
- cxxbridge <input>.rs
--header -
Emit .h file for bridge to stdout
- cxxbridge
--header -
Emit "rust/cxx.h" header to stdout
Arguments:
-
[input]
-
Input Rust source file containing #[cxx::bridge].
Options
--cfg <name="value" | name[=true] | name=false>
-
Compilation configuration matching what will be used to build the Rust side of the bridge.
--cxx-impl-annotations <annotation>
-
Optional annotation for implementations of C++ function wrappers that may be exposed to Rust. You may for example need to provide __declspec(dllexport) or __attribute__((visibility("default"))) if Rust code from one shared object or executable depends on these C++ functions in another.
--header
-
Emit header with declarations only. Optional if using `-o` with a path ending in `.h`.
--help
-
Print help information.
-i, --include <include>
-
Any additional headers to #include. The cxxbridge tool does not parse or even require the given paths to exist; they simply go into the generated C++ code as #include lines.
-o, --output <output>
-
Path of file to write as output. Output goes to stdout if
-ois not specified.
--version
-
Print version information.
