guppy
Track and query Cargo dependency graphs.
guppy
provides a Rust interface to run queries over Cargo dependency graphs. guppy
parses
the output of cargo metadata
,
then presents a graph interface over it.
Usage
Add the following to Cargo.toml
:
[]
= "0.1"
Examples
Print out all direct dependencies of a package:
use PackageGraph;
use PackageId;
// `guppy` accepts `cargo metadata` JSON output. Use a pre-existing fixture for these examples.
let fixture = include_str!;
let package_graph = from_json.unwrap;
// `guppy` provides several ways to get hold of package IDs. Use a pre-defined one for this
// example.
let package_id = PackageId ;
// dep_links returns all direct dependencies of a package, and it returns `None` if the package
// ID isn't recognized.
for link in package_graph.dep_links.unwrap
