Convert a Graph
into its Rust code equivalent.
This allows one to generate a Graph
at build time and then insert it
into the binary. This allows large graphs to be used in embedded systems
with next to no cost.

Convert a Graph
into its Rust code equivalent.
This allows one to generate a Graph
at build time and then insert it
into the binary. This allows large graphs to be used in embedded systems
with next to no cost.
Example
use intern_str::{Graph, Segmentable};
use intern_str::builder::{Builder, Utf8Graph};
use intern_str_codegen::generate;
use std::{fs::File, io::{prelude::*, BufWriter}};
let mut builder = Builder::<_, Utf8Graph>::new();
builder.add("hello", 1).unwrap();
builder.add("world", 2).unwrap();
let mut buffer = Vec::new();
let graph = builder.build(&mut buffer);
// Convert to string.
let code = generate(
&graph,
"&'static str",
"usize",
|f, out| write!(f, "{}", out),
);
let mut out = BufWriter::new(File::create("graph.rs").unwrap());
writeln!(
out,
"const GRAPH: intern_str::Graph<'static, 'static, &'static str, usize> = {}",
code,
)?;
