A simple parser and reader for Microsoft Compound Document File.
This includes a basic parser, which validates the format of a given file or a given stream. It includes a reader too, for iterating over entries and for extracting files inside the OLE storage.
Add this to your Cargo.toml:
toml
[dependencies]
ole = "0.1.6"
and this to your crate root:
rust
extern crate ole;
rust
use ole::Reader;
use std::io::{Read, Write};
let mut file = std::fs::File::open("assets/Thumbs.db").unwrap();
let mut parser = Reader::new(file).unwrap();
// Iterate through the entries
for entry in parser.iterate() {
println!("{}", entry);
}
// We're going to extract a file from the OLE storage
let entry = parser.iterate().next().unwrap();
let mut slice = parser.get_entry_slice(entry).unwrap();
let mut buffer = std::vec::Vec::<u8>::with_capacity(slice.len());
slice.read_to_end(&mut buffer);
// Saves the extracted file
let mut extracted_file = std::fs::File::create("./file.bin").unwrap();
extracted_file.write_all(&buffer[..]);
Release notes are available in RELEASES.md.
ole seems to work for rust 1.9 and greater.
