Rust CEF bindings

Rust language bindings and minimal wrapper around the CEF C API. The goal of this library is to enable use of CEF without directly using unsafe or extern code and no more. It is very far away from achieving that goal, but it does make use of CEF possible and easier in simple cases.

Repository Layout

tools contains the code generation tool, based heavily on and using the cef_parser.py and related CEF tooling. It generates Rust wrapper code from the output of the CEF C++ parser, similar to the make_capi_header.py tool in the CEF repository. It has also been extended to parse basic struct and enum definitions in include/internal/cef_types.h.

cef-sys is a rust-bindgen-generated crate. It is pretty minimal templated code from the basic recommended bindgen structure. It invokes tools/make_rust_wrapper.py to generate a list of header files to feed to bindgen.

cef contains the Rust wrappers. The base CEF wrappers are implemented here, such as refcounting and string types, and the auto-generated wrappers are generated and included from the build script by invoking tools/make_rust_wrapper.py.

cef-test contains a sample of how the cef crate can be used.

Build Instructions

• Download a minimal or standard binary distribuion from the CEF build site
• Unpack the archive
• Set the CEF_ROOT environment variable to the resulting directory
• Create a temporary directory in the crate you are trying to run (eg cef-test/release)
• Copy the contents of $CEF_ROOT/Release and $CEF_ROOT/Resources into the temporary directory
• From within the build directory, run cargo run. If you get a cargo error that says "(never executed)", do cargo run from the crate root once first (it should crash) before running it from within the temporary directory.

windows64 is the only target this has been tested on.
