//! `cargo-lock`: Self-contained `Cargo.lock` parser with optional dependency
//! graph analysis. Used by [RustSec].
//!
//! When the `dependency-tree` feature of this crate is enabled, it supports
//! computing a directed graph of the dependency tree expressed in the
//! lockfile, modeled using the [`petgraph`] crate, along with support for
//! printing dependency trees ala the [`cargo-tree`] crate.
