This library provides the runtime for fidl C bindings. This primarily means the definitions of the message encoding and decoding functions. This also includes the definitions of fidl data types such as vectors and strings.
This library depends only on the C standard library, the Zircon kernel public API, and some header-only parts of the C++ standard library. In particular, this library does not depend on libfbl.a or libzx.a. It also does not link against the C++ standard library.
Some of the object files in this library require an implementation of the placement new operators from the standard library's header file. These are usually implemented as inlines in the header.
