Parses the class file format that is used by the Java Virtual Machine version 8.
extern crate classreader;
use classreader::ClassReader;
use std::fs::File;
pub fn main() {
let mut file = File::open("pkg/Test.class").unwrap();
let class = ClassReader::new_from_reader(file).unwrap();
assert_eq!(0xCAFEBABE, class.magic);
}classreader uses the log crate to emit some log messages. They are mainly useful for low level debugging.
Parses the whole rt.jar of OpenJDK 8 without issue. Code is not yet decoded. Apart from that, everything is parsed into suitable data structures.
Strings from a class file's constant pool are currently parsed into a Rust String. It seems that class files may contain code points for surrogate pairs. These are invalid for UTF-8 encoded strings which is what Rust uses. So whenever such a code point is decoded, it is replaced by the Unicode Replacement Character U+FFFD. This happens rarely but it does happen. A log message with info level is emitted.
