Experimental OpenCL bindings for Rust

dynamic_ocl

Experimental Rust OpenCL bindings, focusing on simplicity and safety. Currently very WIP, requiring Rust 1.41+ (beta toolchain at time of writing).

Features

• Minimum overhead
• Support OpenCL versions up to 2.2
• Provides both direct bindings to the OpenCL C API, and higher level, safer, easier-to-use bindings
  • High level bindings can be disabled with a feature flag to avoid bloat if desired
• OpenCL library dynamically loaded at runtime, allowing compilation of a single binary with optional OpenCL support and easier cross-compilation.
• Types are designed with safety in mind, taking advantage of Rust's type system to prevent various types of runtime errors, including:
  • Kernel argument type mismatch
  • Illegal buffer access (e.g. attempting to read from a HOST_NO_ACCESS buffer)
  • Usage of unsafe types with buffers (e.g. types that have invalid bit patterns that could be created by an OpenCL kernel)
