Crate dev_deps 

dev-deps

Dependency health checking for Rust. Detects unused and outdated dependencies. Part of the dev-* verification suite.

Wraps cargo-udeps (unused dependencies) and cargo-outdated (out-of-date versions). Emits findings as dev_report::Report.

What it checks

• Unused dependencies — declared in Cargo.toml but never imported.
• Outdated versions — a newer version exists on crates.io.
• Major-version lag — how many major versions behind the current pin is.

Quick example

use dev_deps::{DepCheck, DepScope};

let check = DepCheck::new("my-crate", "0.1.0").scope(DepScope::All);
let result = check.execute().unwrap();
let report = result.into_report();

Requirements

cargo install cargo-udeps cargo-outdated
rustup toolchain install nightly      # cargo-udeps requires nightly
