Function compile 

pub fn compile(source: &str) -> Result<ExecutionPlan>

Convenience function to compile source in one call.

This creates a short-lived compiler and compiles the source. For multiple compilations, prefer creating a Compiler instance directly.

Example

use xlog_logic::compile::compile;

let plan = compile("edge(1, 2). reach(X, Y) :- edge(X, Y).")?;
