ruskel

Ruskel renders a single-page representation of a crate's public API with all implementation omitted, while still producing syntactically correct Rust.

It has two main uses:

• To provide quick access to Rust documentation from the command line.
• To export the full public API of a crate as a single file to pass to LLMs and other tools.

Features

• Generate a skeletonized view of any Rust crate
• Support for local crates and remote crates from crates.io
• Syntax highlighting for terminal output
• Optionally include private items and auto-implemented traits
• Support for custom feature flags and version specification

ruskel command line tool

ruskel is the command-line interface for easy use of the Ruskel functionality.

cargo install ruskel

Because Ruskel uses nightly-only features on cargo doc, you need to have the nightly toolchain installed to run it, but not to install it.

Usage

Basic usage:

ruskel [TARGET]

Where TARGET can be a directory, file path, or a module name. If omitted, it defaults to the current directory.

Sample Options

• --all-features: Enable all features
• --auto-impls: Render auto-implemented traits
• --features <FEATURES>: Specify features to enable (comma-separated)
• --highlight: Force enable syntax highlighting
• --no-default-features: Disable default features
• --no-highlight: Disable syntax highlighting
• --no-page: Disable paging
• --offline: Don't fetch from crates.io
• --private: Render private items
• --quiet: Suppress output while building docs

ruskel --help

Ruskel has a flexible target specification that tries to do the right thing in a wide set of circumstances.

# Current project
ruskel

# If we're in a workspace and we have a crate mypacakage
ruskel mypackage

# A dependency of the current project, else we fetch from crates.io 
ruskel serde

# A sub-path within a crate
ruskel serde::de::Deserialize 

# Path to a crate
ruskel /my/path

# A module within that crate
ruskel /my/path::foo

# A crate from crates.io with a specific version
ruskel serde@1.0.0

libruskel library

libruskel is a library that can be integrated into other Rust projects to provide Ruskel functionality.

Here's a basic example of using libruskel in your Rust code:

use libruskel::Ruskel;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let rs = Ruskel::new("/path/to/target")?;
    let rendered = rs.render(false, false)?;
    println!("{}", rendered);
    Ok(())
}
