crate-paths-cli

A Cargo subcommand to generate path trees from Rust crates.

Installation

cargo install crate-paths-cli

Usage

Generate a path tree for a crate:

cargo crate-paths --crate-name std --output-path ./std_paths.rs

Output Path

• If --output-path has a file extension, writes directly to that file.
• If no extension, treats it as a directory and writes to {crate_name}.rs within it.

# Writes to ./std_paths.rs
cargo crate-paths --crate-name std --output-path ./std_paths.rs

# Writes to ./generated/std.rs
cargo crate-paths --crate-name std --output-path ./generated

Backends

• Auto (default): Cycles through the backends to find the crate. going from rustup -> local -> docsrs.
• --backend rustup: Force usage of Rustup source (for std lib).
• --backend local: Analyze a local crate in the workspace.
• --backend docsrs: Fetch metadata from docs.rs.
