cargo tree is a powerful Cargo subcommand that generates a visual tree representation of your Rust project's dependencies. It helps developers understand the dependency graph, identify version conflicts, duplicates, and transitive dependencies at a glance.

Installation is straightforward: cargo install cargo-tree. Once installed, navigate to your project directory and run cargo tree to see the full dependency tree, with your crate at the root and leaves as leaf dependencies.

Key features include customizable formats (normal, compact, indented), prefix styles for indentation, inversion to show reverse dependencies (what depends on a package), and filtering for duplicates or specific targets. It supports workspaces, multiple targets, and feature flags, mirroring Cargo's build options.

This tool is invaluable for debugging build issues, optimizing dependencies, and auditing security vulnerabilities in large projects. Output can be ASCII or UTF-8 for better visuals. It processes Cargo.lock and Cargo.toml to reflect exact resolved versions.

Requires Rust and Cargo installed. Inherits Cargo's limitations on large workspaces. Output may be verbose for deeply nested deps.

cargo install cargo-tree
Requires Rust stable toolchain.

cargo tree --duplicates --format compact
Shows compact view of duplicate deps.

normal: Default tree.
compact: One line per dep.
indented: Indented list.

Developed by Embark Studios in 2018 as an open-source tool. Transferred to sfackler/cargo-tree in 2020; actively maintained with regular updates for Cargo compatibility.
