Creates graphs of crates from cargo_metadata metadata.

Usage

use krates::{Builder, Cmd, Krates, cm, petgraph};
fn main() -> Result<(), krates::Error> {
    let mut cmd = Cmd::new();
    cmd.manifest_path("path/to/a/Cargo.toml");
    // Enable all features, works for either an entire workspace or a single crate
    cmd.all_features();

    let mut builder = Builder::new();
    // Let's filter out any crates that aren't used by x86_64 windows
    builder.include_targets(std::iter::once(("x86_64-pc-windows-msvc", vec![])));

    let krates: Krates = builder.build(cmd, |pkg: cm::Package| {
        println!("Crate {} was filtered out", pkg.id);
    })?;

    // Print a dot graph of the entire crate graph
    println!("{:?}", petgraph::dot::Dot::new(krates.graph()));

    Ok(())
