Expand description

Parses and serializes the JSON dependency tree embedded in executables by the cargo auditable.

This crate defines the data structures that a serialized to/from JSON and implements the serialization/deserialization routines via serde. It also provides optional conversions from cargo metadata and to Cargo.lock formats.

The VersionInfo struct is where all the magic happens, see the docs on it for more info.

Basic usage

The following snippet demonstrates full extraction pipeline, including platform-specific executable handling via auditable-extract and decompression using the safe-Rust miniz_oxide:

use std::io::{Read, BufReader};
use std::{error::Error, fs::File, str::FromStr};

fn main() -> Result<(), Box<dyn Error>> {
    // Read the input
    let f = File::open("target/release/hello-world")?;
    let mut f = BufReader::new(f);
    let mut input_binary = Vec::new();
    f.read_to_end(&mut input_binary)?;
    // Extract the compressed audit data
    let compressed_audit_data = auditable_extract::raw_auditable_data(&input_binary)?;
    // Decompress it with your Zlib implementation of choice. We recommend miniz_oxide
    use miniz_oxide::inflate::decompress_to_vec_zlib;
    let decompressed_data = decompress_to_vec_zlib(&compressed_audit_data)
        .map_err(|_| "Failed to decompress audit data")?;
    let decompressed_data = String::from_utf8(decompressed_data)?;
    println!("{}", decompressed_data);
    // Parse the audit data to Rust data structures
    let dependency_tree = auditable_serde::VersionInfo::from_str(&decompressed_data);
    Ok(())
}

Structs

A single package in the dependency tree

Dependency tree embedded in the binary.

Enums

The fields are ordered from weakest to strongest so that casting to integer would make sense

Error returned by the conversion from cargo_metadata::Metadata

Serializes to “git”, “local”, “crates.io” or “registry”. Designed to be extensible with other revision control systems, etc.
