Fix Release for v3.4

v3.4.2

Features

• info_string - Returns the library meta-information as std::string::String.
• Added arithmetic(+, -, *, /, %, &, |, ^, <<, >>) traits implementations for all input combinations of Array and &Array types.
• Added a batch(boolean) parameter for logical operation functions - this breaks the API and please change your code where you call these functions accordingly. We are sorry for the inconvenience caused.
• get_revision - Returns ArrayFire Revision (commit) information of the library as a string.
• device_info - Returns a quadruple of Strings indicating the name, platform, toolkit name and computer version of the currently active device.

Fixes

• Fixed trait implementations of {Op}Assign style arithmetic traits.

Fix Release for v3.4

v3.4.1

Features

• Neg trait implementation for object type Array
• New set of following functions that lets the user create an array based on dimensions and a particular DType. Earlier to this addition, data generation functions deduced the target array type using generic type.
  • constant_t
  • range_t
  • iota_t
  • identity_t

Examples

• A new graphics example that illustrates acoustic wave propagation.

Fixes

• A much simplified string passing to C from Rust.
• Fix to Cell structure layout that is used in multiple view rendering.
• Use null::ptr() while passing empty strings to FFI functions instead of passing pointer to 0 length strings.

Rust wrapper for ArrayFire 3.4.0

Features

• Sparse Matrix and BLAS
  • Support for CSR and COO storage types.
  • Sparse-Dense Matrix Multiplication and Matrix-Vector Multiplication as a
    part of af::matmul() using CSR format for sparse.
  • Conversion to and from dense matrix to CSR and COO storage types.
• Faster JIT
  • Performance improvements for CUDA and OpenCL JIT functions.
  • Support for evaluating multiple outputs in a single kernel. See eval!() macro or function eval_multiple().
• Random Number Generation
  • A random engine object to handle setting the random engine type and seed for random number generator engines.
  • Supported engine types are:
    • Philox
    • Threefry
    • Mersenne Twister
• Graphics
  • Using Forge v0.9.0
  • New Functions to render Vector Fields
    • Window::draw_vector_field2()
    • Window::draw_vector_field3()
    • Window::draw_vector_field()
  • Multiple overlays on the same window are now possible.
    • Overlays support for same type of object (2D/3D)
    • Supported by Window::draw_plot[2|3](), Window::draw_hist(), Window::draw_surface(),
      Window::draw_vector_field[2|3]().
  • New API to set axes limits for graphs.
    • Draw calls do not automatically compute the limits. This is now under user control.
    • Window::set_axes_limits_[2d|3d|compute]() can be used to set axes limits automatically or manually.
    • Window::set_axes_titles() can be used to set axes titles.
  • New API for plot and scatter:
    • Window::draw_plot() and Window::draw_scatter() now can handle 2D and 3D and determine appropriate order.
    • draw_plot()
    • draw_plot2()
    • draw_plot3()
    • draw_scatter()
    • draw_scatter2()
    • draw_scatter3()
• New interpolation types to enum InteropType that apply to following functions
  • resize()
  • transform()
  • approx1()
  • approx2()
• Support for complex mathematical functions
  • Add complex support for trignometry functions, sqrt(), log().
• medfilt1(): Median filter for 1-d signals
• Generalized scan functions: scan_func_scan and scan_func_scanbykey
  • Now supports inclusive or exclusive scans
  • Supports binary operations defined by BinaryOp.
• Image Moments functions
• Add get_size_of() function for dtype

ArrayFire v3.4.0 Release Notes URL.

Broken/Replaced API

• The behaviour of Window::draw_plot has been to changed to handle generic plot rendering, 2D or 3D line plots. New functions Window::draw_plot[2|3] are added for dimension specific plot rendering.
• The behaviour of Window::draw_scatter has been to changed to handle generic plot rendering, 2D or 3D line plots. New functions Window::draw_scatter[2|3] are added for dimension specific plot rendering.

Fix Release for v3.3

v3.3.1

Fixes

• Dependent crates(libc, num, rustc-serialize) versions have been bumped up.

Rust wrapper for ArrayFire 3.3

Major Updates

• API breaking change is that error handling mechanism of returning Result objects from functions has been replaced with a callback style error handling. By default, we provide an error handler that panics with an appropriate message when a given function call or operation fails. If the users chooses to, they can also implement the error handler by themselves and call register_error_handler that lets the user set the function that has to handle the error values returned by ArrayFire FFI calls.
• enum Aftype has been refactored to DType
• CPU backend supports aysnchronous execution.
• Performance improvements to OpenCL BLAS and FFT functions.
• Improved performance of memory manager.
• Improvements to visualization functions.
• Improved sorted order for OpenCL devices.

New Functions and Features:

• Scatter plot added to graphics functionality
• New function get_active_backend that gives us the current active backend.
• Improved Array Creation/Generation API
• Added mem_info macro to print GPU memory usage information to standard output.
• Added af_print macro.
• Added traits clone and partialeq to all enums.
• Added traits partialeq and debug to type Dim4.
• transform() now supports perspective transformation matrices.
• Type Array now has the implementations for the compound assignment operations traits. These traits are auto-enabled only if you are using Rust >= 1.8.0 since those traits are stabilized from that particular version.
• A few new member functions are added to object Array.
  • new_strided that lets you created array from strided data.
  • strides
  • offset
  • is_linear
  • is_owner
• Following are the other miscellaneous functions added to the library
  • is_lapack_available - Returns true if ArrayFire was compiled with LAPACK functions enabled
  • is_imageio_available - Returns true if ArrayFire was compiled with Freeimage enabled
  • New member function for Array Object, get_device_id, that gets the device id on which the array resides.

Rust wrapper for ArrayFire 3.2

• Feature parity with ArrayFire 3.2 libs except any CUDA/OpenCL pinned memory related functions.

The wrapper has known issue with ArrayFire v3.2.0 libs due to a single missing symbol af_draw_surface from the native library. Please use ArrayFire v3.2.1 fix release to fix the problem. Any version > 3.2.1 should also work fine.
