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

Note: this is a low-level crate that only implements JSON parsing. It rarely should be used directly. You probably want the higher-level auditable-info crate instead.

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);
