# Java Classfile Parser
[](LICENSE.txt)
[](https://crates.io/crates/classfile-parser)
A parser for [Java Classfiles](https://docs.oracle.com/javase/specs/jvms/se10/html/jvms-4.html), written in Rust using [nom](https://github.com/Geal/nom).
## Installation
Classfile Parser is available from crates.io and can be included in your Cargo enabled project like this:
```toml
[dependencies]
classfile-parser = "~0.3"
```
## Usage
```rust
extern crate classfile_parser;
use classfile_parser::class_parser;
fn main() {
let classfile_bytes = include_bytes!("../path/to/JavaClass.class");
match class_parser(classfile_bytes) {
Ok((_, class_file)) => {
println!(
"version {},{} \
const_pool({}), \
this=const[{}], \
super=const[{}], \
interfaces({}), \
fields({}), \
methods({}), \
attributes({}), \
access({:?})",
class_file.major_version,
class_file.minor_version,
class_file.const_pool_size,
class_file.this_class,
class_file.super_class,
class_file.interfaces_count,
class_file.fields_count,
class_file.methods_count,
class_file.attributes_count,
class_file.access_flags
);
}
Err(_) => panic!("Failed to parse"),
};
}
```
