mFAST is a high performance C++ encoding/decoding library for FAST (FIX Adapted for STreaming) protocol.

For more information, please read the article.

For build instructions, please read the wiki page.

[03/13/2016] mFAST has changed the licence from the LGPL v3 to the BSD 3-clause “New” or “Revised” license.

From now on, mFAST require C++ 11 to compile. You can check out the version with tag name "v1.2.1" if you need a C++ 03 only solution.

mFAST has limited support for FAST protocol version 1.2 now. That includes the new define and type tags in the FAST XML specification and the new enum/boolean types. In addition, the generated sequence types support iterators now. However, there is no support for SET, BIT GROUP and TIMESTAMP yet.

If you have used mFAST 1.1 version, please notice there are some backward-incompatible changes. First, to make a existing field absent, please use msg_mref.omit_fieldName() instead of msg_mref.set_fieldName().as_absent(). Second, if you have developed your own visitor for mFAST cref/mref types, the visitor has to be able to visit the new enum cref/mref types.

• OCI has successfully translated the mF AST source code into asm.js (an efficient subset of JavaScript).
• The asm.js version of mFAST when used with Socket.io enables high volume data exchanges between browsers and servers.
• This is an ideal data format for streaming graphs and feeds to web and mobile clients.
  • It can also go the other direction to stream from web and mobile clients.
