flow_macro

See also: Code docs

Flow is an attribute macro to be used on the structure that provides an implementation for a function (by implementing the FlowImpl trait), so that when compiled for the wasm32 target, code is inserted to help read the inputs, help form the outputs and allocate memory (alloc) as well as serialize and deserialize the data passed across the native/wasm boundary.
