OpenCL C FFI bindings for the Rust programming language.


Rust FFI Bindings to the Khronos OpenCL C language headers, see the OpenCL Resource Guide.

The API for OpenCL versions and extensions are controlled by Rust features such as "CL_VERSION_2_0" and "cl_khr_gl_sharing". To enable an OpenCL version, the feature for that version and all previous OpenCL versions must be enabled, e.g. for "CL_VERSION_2_0"; "CL_VERSION_1_1" and "CL_VERSION_1_2" must also be enabled.

The default features are "CL_VERSION_1_1" and "CL_VERSION_1_2".

Rust deprecation warnings are given for OpenCL API functions that are deprecated by an enabled OpenCL version e.g., clCreateCommandQueue is deprecated whenever "CL_VERSION_2_0" is enabled.

The Rust FFI files attempt to match the format and layout of the original C source files instead of bindgen output files to ease maintenance.
