Usage

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

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(())

} ```

krates can also be used if you use cargo as a dependency. It doesn't depend on cargo itself since cargo moves quickly and we don't want to artificially limit which versions you use, but, at least with the current stable cargo crate, the following code works well.

```rust fn getmetadata( nodefaultfeatures: bool, allfeatures: bool, features: Vec, manifestpath: PathBuf, ) -> Result { let config = cargo::util::Config::default()?; let ws = cargo::core::Workspace::new(&manifestpath, &config)?; let options = cargo::ops::OutputMetadataOptions { features, nodefaultfeatures, allfeatures, nodeps: false, version: 1, filter_platforms: vec![], };

let md = cargo::ops::output_metadata(&ws, &options)?;
let md_value = serde_json::to_value(md)?;

Ok(serde_json::from_value(md_value)?)

} ```
