Embedding a Flow in Rust

Hydroflow's surface syntax is typically used within a Rust program. (An interactive client and/or external language bindings are TBD.)

The surface syntax is embedded into Rust via a macro as follows

fn main() {
use hydroflow::hydroflow_syntax;

pub fn example() {
    let mut flow = hydroflow_syntax! {
        // Hydroflow Surface Syntax goes here

The resulting flow object is of type Hydroflow.
