facet-cargo-toml

facet-cargo-toml provides typed Rust models for Cargo.toml manifests and Cargo.lock files, parsed through Facet-powered TOML support.

It is useful when tools need to inspect Cargo workspaces without treating manifests and lockfiles as unstructured TOML tables.

Example

rust

use facet_cargo_toml::{CargoLock, CargoToml};

let manifest = CargoToml::from_path("Cargo.toml")?;
let lockfile = CargoLock::from_path("Cargo.lock")?;

if let Some(package) = manifest.package {
    if let Some(name) = package.name {
        println!("package: {}", name.value);
    }
}

println!("locked packages: {}", lockfile.packages.len());
# Ok::<_, facet_cargo_toml::Error>(())
