flow_impl

This crate defines a trait that implementations of flow 'functions' must implement in order for them to be invoked by the flowrlib (or other) runtime library.

Derive Macro

Also, in the flowimplderive subdirectory a Derive macro called FlowImpl is defined and implemented.

This should be used on the structure that implements the function, in order that when compiled for the wasm32 target code is inserted to allocate memory (alloc) and to serialize and deserialize the data passed across the native/wasm boundary.
