//! # [![](http://meritbadge.herokuapp.com/ocl)](https://crates.io/crates/ocl) | [GitHub](https://github.com/cogciprocate/ocl)
//!
//! Rust implementation of the [OpenCL™ API].
//!
//! Some versions of this documentation are built from development branches
//! and may differ slightly between what is on crates.io and the master
//! branch. See the [repo page](https://github.com/cogciprocate/ocl) for links
//! to both versions.
//!
//! Please report unclear documentation or places where examples would be
//! appreciated by filing an [issue].
//!
//!
//! ## Foundations
//!
//! For lower level interfaces and to use OpenCL features that have not yet
//! been implemented on the `standard` (high-level) interface types, see the
//! [`ocl-core`] and [`cl-sys`] crates.
//!
//!
//! ## Help Wanted
//!
//! Please request or help complete any functionality you may need by filing
//! an [issue] or creating a [pull
//! request](https://github.com/cogciprocate/ocl/pulls).
//!
//! Keep an eye out for places where examples would be useful and let us know!
//!
//!
//! ## Feedback appreciated
//!
//! Suggestions and nitpicks are most welcome. Don't hesitate to file an
//! [issue] just to offer constructive criticism.

pub mod prm {
    //! OpenCL scalar and vector primitive types.
    //!
    //! Rust primitives may have subtly different behaviour than OpenCL
    //! primitives within kernels. Wrapping is one example of this. Scalar
    //! integers within Rust may do overflow checks where in the kernel they
    //! do not. Therefore OpenCL-compatible implementations of each of the
    //! types are provided so that host and device side operations can be
    //! perfectly consistent.
    //!
    //! The `cl_...` (`cl_uchar`, `cl_int`, `cl_float`, etc.) types are simple
    //! aliases of the Rust built-in primitive types and do **not** behave the
    //! same way that the kernel-side equivalents do. The uppercase-named
    //! types, on the other hand, (`Uchar`, `Int`, `Float`, etc.) are designed
    //! to behave identically to their corresponding types within kernels.
    //!
    //! Please file an issue if any of the uppercase-named kernel-mimicking
    //! types deviate from what they should (as they are reasonably new this
    //! is definitely something to watch out for).
    //!
    //! Vector type fields can be accessed using index operations i.e. [0],
    //! [1], [2] ... etc. Plans for other ways of accessing fields (such as
    //! `.x()`, `.y()`, `.s0()`, `.s15()`, etc.) will be considered in the
    //! future (pending a number of additions/stabilizations to the Rust
    //! language). Create an issue if you have an opinion on the matter.
    //!
    //! [NOTE]: This module may be renamed.
